Yeah, that's probably the most relevant question, when was the file tested/released and against which databaseversion. There are two lines of thoughts I have right now, one, it has to do with specific nations, which means that if you edit one of those nations things with assigning teams to the Europa League go wrong (essentially maing it a teamcount issue). That would explain that some people report their files work. The second looks to be the more logical casem which is that SI broke the Europe League. Is there any change or bug on the Europa League that anyone is aware of?
Btw, my boss thinks my thoughts are worth a bit more than a penny
