I tried loading another save that hasn't been loading... I found this a ways up in the logs from where the error is recorded. Hope it means something to someone that can help. I also posted the portion that gets submitted below.

I'll post the error that was sent to Dark God here as well. I don't know how much to post... so I just took from the error to the bottom of the log file. (I astrixed out the port numbers... no idea if they're important. Let me know if you actually need them)
