I returned recently to the game when I heard of the new update/DLC (have not purchased). Updated my install of the game as of December 3rd I believe - tried to join a few servers and I was getting an error regarding ai_bliss.pbo file. I thought I was initially getting an error that said I didn't have the file/it was not found (similar to this ticket https://feedback.bistudio.com/T146874 ) - however now I am getting the error return as "Client contains PBO which is not part of server data: [DayZ install path...]\bliss\addons\ai_bliss.pbo"
I use the launcher, but have no mods installed (I initially installed a few, was having trouble getting them to update/sync, so I removed them/didn't bother).
This makes the game unplayable until you find a server that works (through trial and error). I have not tried to delete the file as I was getting errors related to it NOT being there prior - so which is it? Do I need it? Or am I not supposed to have it?
