A friend and I are having this issue on our multiplayer save. The bug remains in singleplayer, for the both of us(he was host and sent it to me), so it should be bound to the savegame. Neither of us have the problem in our other saves, old or new.
I forget exactly which version it was made in, but it worked fine 2 patches before the Titan update, maybe the one before. The bug remains in the current latest version(r864, unstable). We have no mods active in the save.
Obviously saving/reloading does not work, since that’s the #1 thing we tried, and have tried several times.
My description of the bug:
We saved the game during a lightning/thunderstorm, and when we reloaded it we thought it was a bit… aggressive, so we joked that we had angered a lightning god and tried to keep our hearthlings inside to wait it out. A day passed, and the sun came out… still crazy lightning and thundr.
Holy hell! That’s terrifying! This is due to a save incompatibility with pre-A24+ unstables. Good news: it shouldn’t be possible for this to happen on saves made after A24+ (release 860 onward). Bad news: that save is sadly cursed forever with the anger of the lightning gods.
