undamageable mobs Near Diamond Shrines and Warping Pinned

mobs near diamond shrine cant be damaged until you rush the mob and hope you can get it to kill them. Also i understand the headhunter warps but too be teleported into a corner that glitches you stuck??? Seriously guys, we've spent enough on this game to get these bugs worked out, less cosmetic junk. Can you actually make sure that items are doing what the description says it does? Can we get a good patch and not more NERFs, excuse me balancing's?
