I was playing tonight on 1.1.2 with a new character that had the Clockwork Knight tree. I bought Rocket-Powered Punch while on dungeon level 1 and tried to use it to move some Dwarven Educational Grates so I could get at a blocked section of the level. To my surprise, Rocket Punch no longer pushes grates at all! It still pushes enemies, items, and other furniture (I tested on levers and objects in a Brax room). Was the change to Rocket-Powered Punch intentional?
The change, actually, appears to be to the grates themselves - the last polearm skill will push around items, but specifically not grates. I have no idea if this is intended.
Did you save and load the game at any point before pushing the grates around? I have noticed that at times, things I could push around that if I have to reload I can't push them around anymore. The reload was to a point just turns before I pushed a grate and I couldn't push it afterwards.
Huh. Just tried again with a fresh character and rocket punch pushed the grates just fine. Thanks for the suggestion, LionsDen. I honestly don't remember if the other one was saved and reloaded (been through a lot of new characters recently ) but that could have been it.
Going to a new level will also fix that problem on the new level, at least until you have to load again. Glad I was able to shed a little light on this.
