I got to the place where you have to use the flame mask in Hexen and pressing the space bar in front of the line which activates the mask's script crashes the game with the following error:

- (.PTR_UseTraverse)
- TProgs::ExecuteFunction
- (PTR_UseTraverse)
- SV_PathTraverse
- TProgs::ExecuteFunction
- (PlayerTick)
- SV_RunClients
- SV_Ticker
- ServerFrame
- Host_Frame


Exiting due to external exception

And using the artifact from the inventory doesn't seems to crash...

Fixed that. The fix will not work with puzzle lines with pass-through use type.
