I'm working on a big mag for Heretic, and i have some problems.
First, a screnn of my map :

... and now, the explication of the bugs.
Sometime, when i lauch my map, a weapon (the firemace) appears

... or not

There is another bug, and i don't know if i come from UDB or Gzdoom
Sometime, if i split a little sector and lauch the game, Gzdoom freeze.
If i "ctrl-z" and relauch the map, Gzdoom start normally.
Any explications to solve this problem.
