So I have been progressing score in Blackrose Prison in hopes of soon getting the unchained title, we spent hours and hours learning mechanics, learning spawns, learning what mobs to focus first, to the point where our group is only 4 deaths off deathless and 3 minutes off speed. However, our biggest set back at the moment, random crashes, by every group member. Randomly either after one of our few deaths or just mid fight one of us (and i know other groups suffer from this) will just go invisible and DC without warning. This is nearly everytime we go in, and its multiple peopel suffering from this in multiple groups. How are we meant to progress here if 4/5 runs we have a DC randomly. There is no lag before, no warning just poof DC.
Picture below

As you can see by death counter we had this multiple times in one run.
