The problem first occurred on either the first mission or the second and remained throughout the entire task force. The first mission requires the team to fight 50 Rularuu in the open world so if it did occur I simply didn't notice it. Most likely though it was occurring. I didn't notice until I tried to open the first mission door however. I still received a Notice of the Well and Reward Merits upon completing the Task Force.
I did not switch alignments or do anything abnormal during the taskforce. From initially starting the taskforce (I was team leader) to when I first noticed the problem (it was not occurring prior) I spoke with Dr. Quarterfield and began the task force. Did the first outside mission of defeating 50 Rularuu and then tried to access the first mission door to which I noticed I could not enter. I have been unable to upload a photo, but I have sent one to GM Coldspark on Discord as well as during my time being unable to access the missions I had uploaded a random screenshot on Reddit which also happens to address this problem along which a text error which I will be addressing in another thread after this. I tried logging out to the desktop as well as back to character select. Neither addressed the problem. I went along with the entire team throughout the whole taskforce across multiple zones. The taskforce takes us to Peregrine Isles, Brickstown, Firebase Zulu, and Talos Island. Despite all of these reentry methods I still was facing the same error.
