About weather

[xoft]

Your proposal sounds nice, but in my understanding we would still be making a check each tick, now whether the interval was reached.

Yes, but the check is much less strain than an extra thread. The check is a simple substraction and then comparison, about four CPU instructions. An extra thread means extra thread context switching and synchronization.

Better yet, make worlds without weather skip weather altogether (small change to world.ini)

Implementation details, of course.
