Hello,
The game froze/locked up when using a ladder (kick down ladder south of the two Crane jump puzzle) in Nameless Pass.
After closing NRftW I used Windows Disk Cleanup as I had a low disk space alert (deleting the 66 MB from default checkboxes) .
Log back into the game to continue my run… Both my second Character (18, INT mage) and second Realm I was in at the time of the freeze are now gone. There is no reset option.
We go… AGAIN!
