There seem to be at least three different variants of the infamous stuck character bug:

 

1. Triggered by weapon-swap in mid-reload animation (reproducible) 

-> Character can't be selected by clicking on toon or portrait, but can be selected by dragging on the ground for the rectangle

-> When selected, weapon sets and modes can be swapped, but won't respond to commands

 

2. Triggered in combat for unknown reason

-> Character can be selected normally and responds to all other commands than move; if close to map exit, can exit map and he will follow, but will remain unresponsive

 

3. Triggered when character falls in combat due to stamina hitting zero; when gets up, is unresponsive as in (2) above

-> Behavior same as in 2. Could be the same bug.

Hi OP!

 

Same thing happened to me, switched weapon sets in the middle of a fight and my character got stuck/frozen after combat. I think it was in the middle of an animation too. 

I get this sometimes, usually when characters are equipped with ranged weapons, but not always. They will get stuck in reload or aiming animations.

When this bug crops up, I can usually fix it by saving my game and reloading.

Yes, that works.

 

I haven;t tested extensively, but it seems to me this occurs more often if the character that gets stuck was hit by a paralysis type effect while in combat. Anything that prevents them from moving.
