Bug list from the Alien chapter
As a reminder the Alien chapter pack is 12 euros :
Gameplay bugs :
Since 7.7.0 acidic blood add ons don't work anymore as shown in the following clip :
It's one of the most fun add ons on xeno and it's been 5 month since this bug is there and it's still not fixed while being an add ons that straight up don't work, to reproduce this simply try to activate the add ons (so just go out from a tunnel) it will activate the first time you exit a tunnel and then It will no work at all for the rest of the game. It's the most fun add ons on xeno and since this bug you can't run it because it's just not working.
Since 8.2.0 the xenomorph cannot hit a survivor when he is putting down a turret as shown in the following clip :
Before if a survivor was in the animation of placing a turret you could hit him removing him a health state and breaking the turret (that's logic, I hit him) but now if the survivor is in the animation of installing the turret him and the turret are both completely immune to be hit, you can try to m1 or m2 it's just don't working anymore. To reproduce this bug simply try to hit a survivor when he his installing a turret.
Cosmetics bug :
Since 7.7.0 Ripley skins has a problem, her right hand is resting in her body as shwon in the following screenshots :
As you can see her hand is glitching in her body (as a reminder this dlc is 12 euros and ripley Aliens outfit is 10 euros in auric cells wich is not cool when the skins are broken 
).
Finally Rain Carradine legendary skin for Ripley (15 euros) is also bugged, when she lift her arms (for unhook herself for exemple) the textures seems to strech creating a ugly visual bug where her skin and shirt is weirdly bending (this bug is also happening on Ripley others skins but that's less visible) :
I was hopping for the new version of the game to have at least one of those bugs fixed (since some of them are here since april) but no so that's why I did this giant post to report every bugged I noticed in the Alien chapter pack.
