I am hosting a server for a few friends of mine. They have been able to join just fine in the past, but latley I'm getting a problem where one of them (Lisa) crashes to desktop every time she joins the server. This started a few nights ago, and she was able to joint just fine earlier in the day.

My other friend, Doug, also started to have the same problem. 

The server contained a few mods, but I removed them and the problem continued. None of my friends have mods loaded onto their local machine.

I believe this is very similar to an issue I have seen discussed online where people crash when they try and load back into a server and they are near an asteroid (Both Doug and Lisa are near an asteroid).

I have included logs from Lisa and Doug, as well as the saved game file. The game is a "Never Surrender" scenario.
