Disclaimers

• I have searched the issue tracker to check if the issue has already been reported.
• My issue happened while using mods.

What happened?

I tried to search, but didn't see any similar log lines mentioned.

When playing online with a friend in a private server, the server crashed during a fight with crawlers or spinelings. We restarted from last save and it crashed again at the beginning of a fight with the same creatures.

I tried to recreate it with a build from this source code on github. I created a multiplayer server from the in game menu again, but did not have anyone else to join me so it was just me. The fight with the creatures happened again but the crash didn't happen that time. The save is overwritten now sadly :(

Reproduction steps

Be in a multiplayer (from the in game menu) session with a friend and get into a fight with spinelings.

Sadly that is as much as I know. We saw the crash happen twice for the same reason (title of this discussion) but I couldn't reproduce it with a build from the source code and without a friend.
