[Closed] A consistent crash every time I try to test my map.

[Codename_Delta]

I'm trying to test an in-development GZDoom (UDMF) map I'm making, and every time I try to launch GZDoom 4.7.1 in Ultimate Doom Builder to test the map, it crashes every time.
Stuff I'm using:
Ultimate Doom Builder to make the map.
The OTEX texture pack for it's gorgeous additional textures.
GZDoom 4.7.1 to test the map.
and that's all.

I managed to save a crash report though:

We need the map that is causing the crash.

Oops, sorry.

I've fixed it.

For some reason purple particle fountains were causing it.

If it crashes we need to know why. This shouldn't happen.
