Duration in modifiers

[Wave]

Helloes!

Is there some logic with the durations? -1 is until the game ends and 100 seems to be 100 days. I'm looking for 100 years long but if I try 36500 (days which would be 100 years) I get a crash.

Can someone help me up a bit?

Try duration -1 and then make event with mtth 100 years that will revoke it. I know it's not exactly what you want, but it's quite late and i don't have any better idea at the moment. At least we get some ideas out there.
