For Psiclone no, for Flame Glove yes.
Makes sense.
1. Middle-clicking "Fat Zombie" and "Mongorn Savage" in the "Sell/Sack" screen doesn't display their UFOpaedia pages.
I've never used (or known about) this feature, so I have no idea what you're talking about. I can check, but I have added these units like any other unit in the game, so I can't really do much. ¯\_(ツ)_/¯
I've checked some more, though far from everything yet. It does not seem to work for other living "Strange life forms", rented cars and vans, Red Ops, Red Dawn Pioneers, weapon clips (not sure if they need it) and some Hybrid prisoners. It works for weapons, animal corpses and most human prisoners:
Didn't work for:
public vans and public cars
weapon clips
Zombie
Spikeboar
Mongorn Savage
Giant Spider
Gilldog
Giant Beetle
Deep One Servant
Hybrid Worker
Red Dawn Pioneer (both)
Red Ops (both)
Worked for:
Leather Coat
all weapons
Alien Fuel Trace
First Aid Kit
Bone
Skull
Alien Communicator
Psiclone
Red Dawn Memory Card
Durathread
Durathread Manufacturing
Alien Alloys
Zombie Corpse (and probably all other corpses)
Zombie Parasite
Disciple/Priest/Chosen of Dagon
Black Lotus Follower/Warrior/Witch/Footman
Red Dawn Ganger/Lad/Coordinator
EXALT Infiltrator/Goon/Enforcer
So, it's either living animals or cases when several things have the same Ufopaedia page.
Some agents carrying a Xeno shield appear without it in the inventory screen.
I've never seen it, and all code looks fine. Are you sure it's not an installation issue?
I copied UFOEU and TFTD files to their folders in /usr/share/openxcom/UFO/ and /usr/share/openxcom/TFTD/ then unpacked the mod and copied the directory XComFiles to ~/.local/share/openxcom/mods/ What can be wrong?
Have you tried my file on your machine?
I found and researched a sledgehammer (on a tomb guardian), got a message that I can now buy it, but it still doesn't appear on the purchase/hire screen. Bug?
Unlikely. No idea how I could break it if I wanted, anyway.
Could I be looking at the wrong part of the list? Where should it appear? Between crossbow and wooden club, like in Ufopaedia?
As for Ctr-J, it deals stun damage to all enemies.
Like dart pistol and rifle? Thanks.
Robots and Zombies are immune to regular stun damage, so it won't work on them. Instead, try using Electric-type weaponry (aka stun batons and the like) to knock them out (or at least the undead, no idea if robots can be stunned).
Yes, both can be stunned by taser pistol, electric club and stun rod. Hitting with a shield works on zombies, but isn't very effective.
