We are playing on 1.12.2 with the latest forge, and tornados and other big storms are extremely rare. We already changed the amount of days between tornados to 0 and 1 but neither got us any more tornadoes. Is this a bug, or are there other settings that we can tweak to make them occur a lot? Thanks!

It isn’t a bug I would just reinstall the mod by deleting the mod file and downloading the a new one with the latest version this will reset ALL mod settings but should fix the problem. I also noticed that if you are by a ocean or a tropical place there is a higher chance of a tornado spawning.

We already have the latest version, and a fresh config didn't change anything. Which other settings could we tweak to up it a bit? Also, how does this work on a superflat where there might not be any oceans or tropical places?

Change numbers =100 you will get storm intense found in the Storm.cfg also change landbasestorms=-1 to 600
