In Hexen, if player already has a 4th weapon and take a piece of 4th weapon, a message will appear telling that weapon "is assembled", then game will crash. NOTE: It happens only if both mana values are low enough. About 150 or less. Looks like it is connected with how much mana weapon piece gives.

ERROR: Reference not set to an instance of an object

I've had that happen when taking the head piece when I already have the head piece of the blood scourge in hexen. The area where the magic bridge is that leads to two places, one with a teleport. I think Griffin Chapel.

I can confirm this bug persists in 1.31 ! Usually it doesn't happen, but once per several tries (roughly) it does. Sometimes it's a piece I don't have, sometimes it's after I already assembled the weapon and find spare parts.

Reference not set to an instance of an object

Would running with -debug yield more information ?

Yes, it should at least give a stack trace, to make it easier to determine where the problem is ocurring <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt=":)" title="Smile" /><!-- s:) -->.

I hope this helps. Note I had to disable noclip because "Bridge" (floating sparks) doesn't like cheaters ! <!-- s;-) --><img src="{SMILIES_PATH}/icon_wink.gif" alt=";-)" title="Wink" /><!-- s;-) -->

Try this test wad (Hexen, MAP01), it appears to crash for me after the 4th or 5th weapon piece.

Fixed.
