Weird weather removal

Properly removed weird weather by disabling the condition in which it was created.
Our smiling god blesses us with approving warmth.

This was being done on the old code, so I just mimicked it. I forgot to do this on the first PR, but it should have been included there.
Anyway, if it's a bug, it was a bug also before the change, so it should be managed separately, I think.
