Hello, i been also having the same issue, to be honest the list goes on. Before this recent crash, when i opened the map it even states it could not update from Revision Control, nor was i able to update anything to it. Once again last night I was given this as a crash report
Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000038

I found out how to make a work around for it by deleting the world and reinstalling it from the “RC”, but i am tired of having to repeatedly restart my progress because of this glitch.
