Zandronum

Hey everyone. New member here.
I've been having a great time playing Zandronum. It's a great sourceport, and it's my go-to for multiplayer Doom. And I've only had one problem so far. It has sort of become an issue while playing singleplayer. I've noticed that all enemy attacks do minimal damage on any difficulty that I play on.
I usually play on Ultra-Violence, and I noticed that when I'm hit by anything, be it Imp fireballs, gunshots, or melee attacks, I either take no damage at all, or I only take a small amount of damage (1-3 hit points). Keep in mind that I have no armour on while this is happening. The only constant damage I can regularly receive is floor damage.
I tried playing GZDoom on Ultra-Violence, and I took normal damage each time I was hit.
Could someone help me fix this? Everything is becoming too easy.

Have you tried deleting zandronum and re-installing? Just to make sure you don't have anything messed up in your config files or such.

Yes, I actually uninstalled it and reinstalled it after an issue I had with joining severs, and it fixed that. But the damage issue is still there. I've also gone through my config files and I can't find anything in there that would help.

Isn't your SV_Coop_DamageFactor altered?
