Can't get ultimate doom visor working

[invictius]

The error I get on completely clean installs of source ports, with both 1.50 and 1.71 is:

Script error, "UDV_v1.50_A_BASE_BDv19_GZDoomOnly.pk3:actors/flashlight.txt" line 14:
Unexpected token string constant "UDVflashlightHoriz"

Running it as per instructions that come with the mod.

I was able to replicate your issue by launching it with Zandronum 2.1.2. If you want it to work properly, you'll have to use one of the 2.1 builds of GZDoom, which you can find here: http://devbuilds.drdteam.org/gzdoom/
