Has anybody a clue what to do if rules are stuck?
I deleted several rules from my GP and even deleted them in my folder, but they still are applied.
Is it possible that this glitch appears as I didn't deactivate the rules?
I lost several matches in the meantime as especially my rule for 4th down is still in effect all of the game although it was written for end of 2nd and 4th quarter.

This might need to go into the Bug Box/be a PM to JDB. I have deleted rules before without encountering this issue

Both done. The main problem of this deleted but still applied rule is that it works regardless of the original criteria (Timing 2nd and 4th quarter, 2:30 - 0, 0-1yds, only in opponent territory (40 - 0)).
E.g. I have observed 1 occasion mid 1st quarter, own 10, 11 yards to go :-(

**** that's rough. Hopefully it gets resolved soon for you. If you had the rule saved you could reload it and then deactivate it to see if that resolves it

Hmmm. Way back in 2019, I encountered a situation where i could not put my rules in my preferred priority order.
I forget who made the suggestion - and theirs also came from a different rules related issue, but the solution was to delete every rule and then re-create them.
Jot em down on paper, delete, remake.

It also worked when I could not get my rules to deactivate... hehe.
So, I suggest giving a full deletion of all rules, a cookie/cache wipe, and see what happens when you make 2-3 new ones.
Hope this is helpful, though I realize it's not appealing.

**** city, but it may work.

I think I've found the error. Just a wrong input at a certain rule... 4th down which should've been omitted.

Shame on me... getting old :-D
