I will be investigating this later, but was Wendy present when this happened?

If not, could you send to my discord.gg/3QTAYYCQ today's logs from Documents\Klei\DoNotStarveTogether\backup\client_log?

Umm yes she was!
In fact she thought she triggered it when she saw a spider queen spawn n I quote "popped out of the ground"
I think I tried to asked them if it wasnt a nest but never rly got an answer from it as I thought it was the spider farm I had w 2 queen at it, but they were talking about 2 biomes away

N as for the last part, no sry, I dont have client_log anymore
It's been overwritten already a few times from both starting and restarting after this incident for other reasons, jst now crashed on rollback

That's why I asked for backup, older logs move into that folder

Ah well I also missed the "if not"
Implying you only needed them if she wasnt there
Else I wouldnt of said anything about the log files
