This one happened when walking around by any map and it's random, it sometimes happens, and other times it doesn't, here's the debug info:

- Z_Free
- VDirect3DDrawer::SetSpriteLump
- VDirect3DDrawer::DrawSpritePolygon
- RenderSprite
- R_RenderMobjs
- R_RenderPlayerView
- SCR_Update
- Host_Frame


ERROR: Z_Free: freed a pointer without ZONEID

I'm getting the same problem in Hexen. On MAP02, after you solve the "puzzle on the seven portals" and go across the courtyard and into the gold door all the way on the right. Almost all the way to the back right after the ice crushers I'm getting this: Z_Free: freed a pointer without ZONEID Stack trace: Z_Free <- RunThinkers <- P_Ticker <- SV_Ticker <- ServerFrame <- Host_Frame Vavoom version 1.16.1 Thank you.

As a general note, it also happens on Korax Arena in the docks level, it sometimes sends the error when drawing the translucent water, I don't know if it's because of the GLVIS or something about the renderer.

It definately has nothing to do with glVIS.

I tried regenerating the .gwb with different versions of glBSP and playing it back with different versions of Vavoom, but each time after loading the save game it crashed. I eventually bit the bullet and restarted the level (for the 5th time) and it made it past the sticking point with no problem. Must've been something about that game session. Overall, though, Vavoom is a great game engine. I don't want to submit a bug report without saying that. I could never even so much as come close to it with my admittedly feeble programming abilities (even considering it's a source port) I tried playing strife and I get the same errors as Firebrand. They seem to occur regularly if I go to certain areas of the game like as you look at the power station if you go to the right from there it will crash as an example. Thank you.

But the errors I get are also random, they occur sometimes and sometimes the game can be played past those points.

Okay I found a reproducable error in Hexen. Go to MAP13 and die. As soon as you respawn, it crashes.

Found a reason for this one and fixed it.

Thank you. Can't wait to download it and continue playing!

The problem in initial post also has been fixed.
