That's the best thing regarding the potential for this. This is literally FL26 with Konami vanilla gameplay with AI vs AI mods only! so your right in that with the AI you can see the odd dumbass stuff happening. There is some weird issue where teams don't utilize the wings when players are in space and don't press high properly in those zones.
I know there's a gameplay patch that could help this. just there so many and I feel indeed to learn how to tweak whatever I use too before I go down that rabbit hole.
Vanilla Konami gameplay is important for making PS4/PS5 tactics which will be used for PES Universe and anyone else who needs this imported in for consoles. If it works well on vanilla then it will work well, if not better which whatever mod you have.
