Sorry to burst your bubble, but Cryptic's priorities at the moment probably rank as follows:
1. Server Stability/Crash issues
2. Account/Character Creation/Maintenance Issues
3. Bugged Content Issues Causing unplayable situations (like the complaint here)
4. "Stylistic" bugs (text errors, minor graphical errors)
You can pretty much count on Cryptic being almost exclusively focused on 1 and 2 for the next couple weeks at least. They need to get people in the door and keep them playing past the "free sample" phase and build a dedicated player base. The trick with MMO's is to get a second wave of subscribers and have staying power. If they crash and burn because people can't play the game and give up/move on, it's probably over.
That said, if enough people complain about a specific mission, it can potentially rise in importance to equal 1 and 2, so threads like this are important. But I wouldn't get my hopes up.
Just an observation from someone who used to work in this industry.
The only work around i know of and i've been able to prove is that you need as many people in that 1 mission to start a new instance and that new instance will be able to play out but once its done then well you have another bugged instance.
what they need to do is put a reset timer on it like every other fleet action and deep space encounters so it resets.
well i hope they add the timer and it resets after that timer is up like the other fleet actions.
