1. This is the biggest problem, it's with the Keys, when I get for example Red Key, my friend doesn't have it, and the Red key Disappear so he can't get it, so everytime he wants to get over Red Door, he has to wait for me, and this is annoying, I even have the Share Keys Between Players Option Enabled.
Spoiler: Image1 (Open)2. UAC-Mach-3 Minigun is supposed to show red spot on the top of the gun when it gets hot, this works on singleplayer but in COOP it doesn't work.
Spoiler: Image2 (Open)3. When dual-wielding the UAC-30 Designated Marksman Rifle it doesn't show the dual-wielding ammo below like in Image4, but other weapons such as Sawed-Off Double Barrel show it like in Image3, this happens on SP and MP.

Spoiler: Image4 (Open)Notes:
I'm using Win10 64bit (build 1803), and Zandronum 3.0.
I've also reported this on the tracker https://zandronum.com/tracker/view.php?id=3596.
Sorry for bad English, English is not my Primary
Edit: I've found a workaround for problem #1, it's to use "+sv_cheats 1", and when someone pickup for example Blue Skull Key, I type in console "summon blueskullkey", but this means I have to enable cheats and I don't want that, and Thanks in Advance
