Today I noticed something really odd about monsters a lot of the time in the clockworks, that is probably in relation to the tweak patch we got recently.
Even as deep as T3 certain monsters are sometimes non aggressive. It's more common in monsters that spawn when you enter a the area but I've seen it in monsters that are already there when you arrive as well.
They will just sit there and do nothing, if you shield bump them around they might move once or twice then stop, (or they may potentially attack once, then stop) If you hit them with a sword they are unlikely to respond to the fact that you are killing them.
Sometimes they may still attack if you get right ontop of them, but not as rapidly as they usually would, they will also tend to ignore your presence and not pursue you even after you have walked up and wacked them a few times before running away.
It's most common with the gremlin menders who will just stand there doing nothing even if you injure other monsters in the area, but I've also so far seen it happen with scuttlebots, lichen, and thwackers.
Monsters I have observed so far that don't seem to be effected by this
Retrodes- Although (and I'm not sure if this is a bug) The timing on their eye beams seems to be funky now
Fiends
Lumber
Fiends in general
(In short, it looks like you guys gave some of the monsters out there too many sedatives with this most recent update).

Check patch notes - its a feature. And I love it ♥
Seen a single passive monster in last 50 levels, doesn't really matter to me.
