I've encountered an error in jHexen whereby a two-way portal I need to enter crashes the game upon entrance. I've saved the game right before entering this portal, and I haven't any other saves. I've tried going through this portal with the "stable" 1.9.7 beta, the #199 build, and the (formerly) latest #276 build, and all result in the same crash after entering the portal. Is there a quick Notepad edit or something I can perform to fix this save? Is it irrevocably corrupted, and my only option is to start over completely? Has anyone else encountered a crash like this?
Also, where's the mouselook toggle? I've looked up and down the Controls menu but couldn't find it.
