I know the ZDCMP2 is primarily for ZDoom; but since some GZDoom stuff is included, I figure it should at least not print warning messages:

That one's my bad. I removed those actors when I changed the beam attack to a rail instead of a fast projectile. Didn't think to modify the GLDefs afterward, and while we're on that note, the Soulrender is missing GLDefs too. I'll have to fix those in between rounds.

You can also fix them now, it's your turn anyway

Fixed it in this version. The Soulrender's projectiles have GLDefs too, now.
