Cannot advance side missions progress due to this bug. I mainly play solo on XboxOne and was at WT2 when I first tried to solo this side mission, but was underleveled so backed out after trying unsuccessfully to kill the final boss. At that time this side mission was not bugged and I was able to plant the bombs and destroy the blood caches, prior to the unsuccessful boss fights.
I then continued to level up my character to 350 by doing the Potomac Event Center campus settlement mission and all remaining side missions except for Potomac Relief Camp. I then successfully tackled the District Union Arena Stronghold after Patch 1.03 was applied and reached WT3. I then tried to again do the Potomac Relief Camp side mission at WT3 as that was the only side mission shown on my map. However, when I get to the final blood crates in that side mission there is no prompt on the crates to place the thermite charges and no enemies spawn. I have tried to do this several time, but eacch time no enemies sspawn and there is no prompt to place the bombs on the crates.
I noticed several other players are encountering this same bug and have also noticed that Ubisoft says they have not been able to duplicate this bug.Please keep trying as I am at the point where I need to do the Roosevelt Islan Stronghold and advance to WT4, but am holding off until I can do this side mission at WT3.
I hope this explanation will assist you in fixing this bug as it is extremely frustrating to thos of us with the same issue and who love this game.
Thanks in advance for a prompt response and solution to this problem.
