I have done ~100 ZR runs and have only seen the bug twice. Basically some1 used a cell and it didn't remove the corresponding pathos. Relog worked both times. In fact I only learnt how to solve the problem because some1 else already posted similar findings under ZR thread few years ago.
Quite frankly I don't see why ppl try to make a big thing out of this. So far it has only been reported once on this forum if the update did break ZR more salvage groups would have experienced the same problem. Get over it, it's not like you are going to stop doing ZR until SE admit there is a rare bug in that zone.
