Hey guys, Just encountered another slight bug. I played Heretic and went from the Cathedral to the Secret level. Then the game crashed. I loaded the game into gdb and tried to make a backtrace but this time the game went to the new level correctly. However when I wanted to give it another try the game failed to load from the secret level back to my Cathedral Savegame. I attach the Savegame to reproduce it. Here is what you need to do to reproduce: 1) Load my Savegame 2) Go to the Exit teleporter 3) In the new level press F3 and load my Savegame again --> Game should crash. Oh and here is what gdb spits out:

I hope this helps. If someone telle me how I compile the game with debugging symbols (I am not a CMAKE pro) I can try to get a better backtrace. Regards, Christian

Okay I gotta extend this bug: I can also not finish the level. I attach another Savegame getting you to the end of the level. Crashes everytime...

SVN revision 4354 SEEMS to fix this bug for me. At least I could now advance to the next level.

Yes, it's fixed now.
