It is good that you found that, I was on the swamp starter which skips the first part of the Robinson protocol.
I do not know if this will help, but I have determined that the players map is defiantly effected by this error because I was able to repeat what happened earlier. No CoQ, the players map is intact on reload. Get the C0Q, players map is wiped on reload. Before Exiting. After Reloading.
A fix for this is now available on the experimental branch let us know if it triggers again https://empyriononline.com/threads/v1-5-6-hotfix.98585/ as of this fix I haven't triggered it again in SP & MP.
I'd like to supply some additional logs on this. I am not sure what triggers the crash. Maybe a memory leak from what I read in the last log.
