Modpack Version

v1.0

Describe your issue.

Sometime yesterday the server was hanging, crashed eventually and seems like it rolled back 1-2 hours.
After that, whenever someone opens up the FTB map the client crashes. No matter if you were online during the crash or not.

Latest log is the server crash log from when it happened.
