8. Steps to reproduce the Issue (Optional)

Try to start a MP game using modpack, simultanous turns and default settings with at least 1 AI. Game will load, but crash after less than 1 second.

If you use the initial autosave, it will CTD at the end of turn instead.

Can't do anything without the modpack.

Additional info: The behavior in singleplayer is normal (I can play against AIs using this modpack, no CTDs).

Tried making a new modpack again, still the same result.

I can confirm the issue on my side, with my own 4.17.8 modpack.

I can also say that the 4.17.0 version didn't had the issue.
