I'm not talking about carry capacity, I mean certain heavy items are too heavy to be picked up at all! but there should probably be a UI message that tells you why you can't move an item between characters, pick it up off the ground or out of a chest. because I just spent the better part of an hour testing things before I worked out what the problem was.

So yeah, long story short I have been punished for my Min/Maxing, fairly annoying as medium armor isn't supposed to have STR requirements in the tabletop game, but that's what we have.

Edit: cool work around though, you can drink a STR potion equip the armor you need and the armor stays on after the potion effect is over.
Had the exact same experience; I spent an hour trying to work out why Gimblebock's armor kept vanishing when I looted it; reloaded and reproduced the behaviour twice, then on the third time decided to loot items individually and saw it stay on the corpse. There really does need to be a UI prompt for that kind of thing.
