Made it through 100 seasons with each country, beginning in 2012. Never got the October 25, 2013 crash even once.
World Cup - Doesn't always work, but I can't figure out why it doesn't work in certain years.
Oceania Nations Cup - 2012 3rd place game never gets played, competition does not take place after this.
International Club Competitions:
World Club Championship: 2029 3rd place game never gets played, competition never runs again. I think this could be fixed by moving the competition back to it's original timeframe, which is in August.
Asian Cup Winners Cup: 2013 3rd place game never gets played, competition never runs again.
Country Club Competition issues:
Australia: Closing Stage only gets played during the first season.
Belgian Cup does not get drawn. Fix using Tri-Wasano editor listed earlier in this thread.
Denmark sends teams from First Division to UEFA Competitions instead of from Premier League. Fix: Change the competition prestige rankings, so Premier > First Division.
Ireland - Munster Senior Cup 2nd round gets played first season, third round never drawn. Leinster Senior Cup is never drawn, and never played.
Northern Ireland - Charity Shield runners up not always listed. Not a big issue at all.
Spain - When you use Second Division B, at some point (it's not the same year every time, unfortunately) the promotion playoffs get messed up, and then the following season the scheduling for all the divisions gets messed up from that year forward (teams end up playing all of their games over 12 matchdays). When I ran the game without Second Division B selected, it went 100 seasons without any scheduling issues.
