Just to explain a little better about the kits.
Let's say 1 set of kits = Home, Away & Third kits.
The PL teams have 4 sets of kits. (18/19 & Classic 15/16, 16/17, 17.18)
Most other leagues have 2 sets of kits. (17/18 & Classic 13/14)
If you try to select a PL team against any other league, the computer can handle selecting 6 sets of kits at a time.
When playing PL vs PL there are 8 sets of kits and that's when the computer freaks out and crashes.
So the files themselves are ok. The database is fine. The computer simply can't handle the additional kits or at least I can't find any other issue with the database. Believe me I have tried every test over the weekend
If you want to save some space in the kit folder then search for '_2015.rx3' & '_2016.rx3' and delete those.
Thanks for all your comments and suggestions. Glad you enjoy the patch.
