Wait, do you mean 1.29.3.5? Is there a link for that one on the forums? I tried all the versions I could find some time ago (specifically to see what was the latest version that didn't have the equipment bug) and I didn't even know that existed; maybe I'm just dense and outright missed it.
Plus, as far as I could find, the equip bug happened sometime between 1.29.3.2 (which doesn't have it) and 1.29.3.4 (which does have it), so if it's not in this 1.29.3.5 then my curiosity is piqued to say the least.
