Hacking on PrBoom+ and ran into a visual error

[Phytolizer]

Hello,

I have been hacking on Prboom+ for a while now, adding and changing things that I personally wanted. One of these things is colored blood, a la Crispy Doom. (I don't use Crispy Doom because it isn't MBF-compatible.) I added some code from crispy to r_things.c and the colored blood works in GL and software renderers (!) but I also have this strange artifact showing up on my weapon sprite:

It's fairly rare to observe (at least on MAP01), and only occurs when looking in specific places. I haven't worked with the Doom source code extensively enough to know what that means, other than I messed up translation tables somehow by introducing this to the vissprite_s class. Attached is a full diff of my changes from GZ's GitHub repo.

EDIT: Because git diff missed it, here's the contents of v_trans.h and v_trans.c.

EDIT2: It's on GitHub now. https://github.com/onContentStop/prboom-plus/commit/f9134b06df5091016ac6787210d8afcfc08faaf3
