I did compile new version from source few hours ago and noticed that there are now weights reported on inventory screen, also my soldiers have only around 16TU's while before they had nearly 30.
If I understand correctly weight penalties have been implemented, at least can't remember seeing weights before this in my short trip to UFO:AI world.
One of my soldier has 16.7kg/25kg load and it shows up as red which probably means weight penalties being in effect.
Soldier has following equipments:
Laser rifle
2x DF-L cartridges
Frag. grenade
Flashbang
Medikit
Soldier has also Nano armor.
With bit of testing I found out that it is not possible to wear nano armor without weight penalty which in practice means that can't use medikit at all because only 16TU's is maximum.
Probably balancing of feature is still under way as feature is very new one?
Thought to let you know about what I found out, but might be planned?
What I think is that maybe there is bug making weight penalty so early before reaching that 25kg, but as I'm so new I can only guess and be probably wrong in many aspect, don't hit the face
