ive noticed that with this mod, it prevents anything Solar from working as well as mobs like Zombies an Skeletons Burning

The default behavior is to keep server side rain and thunder off, so im not sure why solar wouldn't work, either way, to get better compatibility set "storms when" to global overcast in the weather gui config.

Which mods solar panels/blocks btw?

In the latest version you released that now has snow, solar works, i had just forgotten to close this, tbh after the tweet youd sent in reguards to this, im not 100% sure if i changed a config option
