Seeding, need to get to my computer to work on it tho, don't remember how it works exactly.

Yup, under league settings if I remember right. I can show u screenshots if I get to my computer.

I reproduced this bug with an edit with 2 transfers added to a player in his Past Transfers and that player became unavailable too(in another league). Might be worth reporting as a bug.

To get the qualified 3rd placed teams, I believe you would need a hidden stage to rank them and to qualify them into the knockout stage. You might need another hidden stage if you want different seeding for 1st and 2nd placed teams in group. At last, you should be able to do the 1st vs 3rd using Place Seedings Together. But if you want specifically 2nd from group A vs 2nd from group B, you need Cup Tie Mappings.

I tried only your file on 2 start dates, July 17th(Small and Large database) and September 18th(Small database), all successfully loaded into the screen where you could choose your own team. I also did one ending at the screen in the game and saved the game.

I did try my own file(Ali-saleha to Turkspor on March 7th) without the leagues and it didn't crash. I don't remember if I had tried yours, would try it if I get back onto my computer.

This is a save game where the manager went on holiday until March 6th, after that I go on holiday day by day and Ali-saleha is on Berlin Turkspor 1965 team at March 8th. The setup of mods is the same as the one I provided above. I suspect the German mod by D4n1v4l is the reason that the game crashes, especially that it crashes even when I chose only Oberliga and above. Of course I can't be sure, maybe even when I pick Oberliga or above, the 6th division is loaded partly. One way to test this is to make a clean Germany 6 Division database(Probably no need for advanced rules?), it will provide insight whether if the transfer causes crash or not.

My comment is incomplete, I can't upload screenshots and files right now, tested on new comments. I don't know if it is my internet(I tried my mobile it still failed) or it is this site's maintenance Edit: Fixed

@Zachary Whyte I ran @Kruj file with a verified for 24.3 Germany league mod and it worked for me.

Sorry, I locked myself out of my home just now First, I suggest you to save before removing the play-offs because you would like to have them there to retain the structure. Also, even when I don't change anything meaningfully(I only changed minimum team from 16 to 10), I am hit with this and failed the verification. To counter this, under Serbia > Fixture Rules > Rule 1 FIRST > Squad Registration Periods you should copy the Squad Registration Periods using the top left hand side Edit > Copy (Squad Registration Periods) and paste it under Serbia > Fixture Rules > Rule 17 > Squad Registration Periods. The short answer for why is because of squad registration and with you goal in mind, you probably won't be editing squad registration. Removing the clubs is right, changing the required teams numbers is also right and removing play-offs and play-outs(I have no idea what this is, is this the league split?) is a good way to deducing the problem. However, in this case, it might make things more complex, since there are league splits involved and you would need to remove them too, which complicate things too much, I would advice you to just keep things as is and just change the number of teams. The error says that it could not find rules for division with 10 teams, but when you revert back to 16 teams with the change I mentioned, it should verify, so what is wrong here? The logical thing to say would be either rules are defined by the number of teams or you have not changed all the settings that makes 10 teams work, since I made it work. For rules, you could easily find Youtube guides online and after that, you could decide which one is the case here. P.S. Do you know what each stages do?

If you Add Nation Rules, the wizard has two options: Create New Competitions And Rules Add Lower Divisions And Cups To Existing Structure Most of the time you pick the bottom one, what it means is you get full access to the existing structure. To edit a league that already exist, you would need to Convert To Advanced Rules To change the number of teams, you need to do that in the Nation(Serbia) and the Competition(Serbian SuperLeague). If you want to edit the Serbian SuperLeague, you would need to change the Show Rules For to Serbian SuperLeague. This should have answered your first question, lets see how you get on to this, if you need help just type here.

Try this first and see if this is what you want, I will explain later. SerbiaSuperLeague10Teams.fmf

I think you have mistaken what rounds mean, rounds here mean round-robin, so if you have 18 teams in a league, 1 round would be 17 games for each team and 2 rounds would be 34 games. An easy way to verify would be looking into Bundesliga's League Settings

I have no experience in editing with parent and child competitions, but I would imagine that this is the way to go. By the way, I think parent and child competitions might not be what you think to be. Sky Bet Championship doesn't have English Premier Division(EPL) as its Parent Competition, but Vanarama National League North has Vanarama National League North/South as its Parent Competition, might worth looking into how it is set up, or better find guides online

I don't quite know which and where the fixtures section you are mentioning, but if I am to change the number of matches played in a competition, for competitions not in game, I would Add Nation Rules and Add Divisions and setup there; for competitions in game, I would go to Add Nation Rules > Convert To Advanced Rules > Show Rules For (Your competition name) > Stages > Stage(League) > League Settings > Number Of Rounds
