I recently had a large issue which required a senior GM's assistance. Yesterday, a senior GM came by and helped me resolve the issue with my character.
It appears the issue affected 1 more spell that neither of us were aware of at that time. If possible, I require assistance once more

I also have found a 100% reliable way to reproduce the old invulnerable warlock bug (discovered on accident). I was invulnerable, able to move/cast, and was unable to be damaged/cc'd (even by alliance that ran by me). I managed to free myself from this state, but would like to give this information in a more private method than a publicly available bug report tool, as it can be SEVERELY abused.
edit: it appears I am also 100% unable to loot enemies currently, likely due to the above issue.
