Hum I see, I thought Early Access meant "doing the finishing touches and removing minor bugs", but it appears to be more like "still working on the core mechanisms" uh -_-
That is a little harsh ...
We were told that game will be unfinished and bugy ... multiple times, i remember Swen alerting that in every single interview.
Also we dont quite know if this bug was caused by some "allready done" thing colided with some "newely implemented" thing ... or if someone simply broke the "allready done" thing by rewriting some part of the code he was not suppose to (i mean even developers are just humans, and humans do misstakes) ... or if that was some experimental mechanic implemented for testing, that turned out much worse then its creator hoped.

Also note that some (and i dont know how many) things that are implemented wasnt originaly even part of the plan ... or that plans changed based on what people demanded (just play Patch 1 and you will see yourself

) ...
So i would say its not quite fair to complain about bugs in this situation ...
For one, we were warned ...
And for two, IF Larian would want to ... they easily could simply as you said "doing the finishing touches and removing minor bugs", compeltely ignore all feedback and just finish the game the way they see fit.
Personaly im glad they didnt and few smaller or bigger insects here and there seem like small price for it. :P
Another thing I noticed that is frustrating, if I just try to move around an enemy the slightest, I trigger an opportunity attack, but enemies sometimes can come and go right next to my party members without them triggering an opportunity attack (and before you answer that : no, it wasn't a goblin who used disengage as a bonus action, or my character having already used his reaction).
Again, screenshot would be most helpfull to both determine source of problem, and pinpoint it for potential bugreport ... and therefore repair in the near future.

Question tho: Did you have meele weapons equipped?

I often forget to switch my archer back to sword, and waste reaction by that.
Oh, and another thing : Fog Cloud does absolutely nothing. Enemies on the other side of the fog can shoot at you just as clearly as if it wasn't there.
I experienced this bug aswell ... reported it.
