Please explain your issue is in as much detail as possible.
When troops enter a county where attrition kicks in, the timing of when that attrition kicks in is absurdly variable. I've seen it take a month before anything happens and sometimes I've lost a huge chunk of troops the same DAY that they entered a country with attrition.

The thing is...this bug has ALWAYS been in the game. I've seen it for a long time and thought it was blaringly obvious enough that it would've been fixed, but I guess not. Attrition should kick in after a set period of time that troops are in a county, perhaps with a small degree of variation. Otherwise it's a roll of the dice that makes no sense. The armies would have supplies with them that would take a set period of time to run out. They aren't going to suddenly starve and lose troops the day they set foot in a county!

Steps to reproduce the issue.
Have a bunch of troops.
Walk them from a county with no attrition to a county with attrition.
May take numerous attempts to see this happen, but it will happen.

Attrition is invariably applied at the beginning of each month as far as I know, same as in EU4. You can abuse this to some degree by timing movements of large troop stacks to avoid or weaken an attrition tick, but it's not necessarily worth the mental overhead.
