I've been playing postal redux on excess postage with nightmare mode on, and upon starting the EZ mart level my rocket launcher began to glitch and explode right in front of me. I tried moving to multiple areas on the map and still experienced the same issue of the rocket prematurely exploding immediately after i fire it.
Additionally I noticed that the flamethrower will not shoot it's ammo in certain areas, wasting the ammo and not doing damage to the npcs. Has anyone else experienced these glitches on the EZ Mart level? Is there a patch I can download to fix it?
