Hey sorry, not sure how I missed this so many times :eek-new:
I think it was an oversight sadly. I personally didn't realise that that ring's function was in game and I repurposed it into the "Steel Grips" feature. So, sorry about that. I wonder if it was something to do with weight limits being removed from game.
Anyway, the whole push mechanic in game was refactored into a single procedure (similar to how poison/slow/freezing was) to make it more malleable to future updates. This is why push previously had different effects from different entities in game. Now, barring any exceptional circumstances, the push mechanics undergo the same "tests" in order to proceed. One of those tests is pusher's level and thus a pusher's level may overcome "Steel Grips".
