Getting an error when trying to enter a flashpoint that says something like: The Party Leader needs to reset the current flashpoint before a new one can be started? Well, if you're having this issue, it's likely you can't enter the flashpoint solo or in a group, even after you've abandoned and re-accepted the quest. Well no problem! Here's how i fixed it for myself: 1. Find a friend 2. Join a group with them 3. Convert to an Ops Group 4. Change Difficulty to Legendary (16) 5. Reset all Active Flashpoints 6. Drop Group 7. Enter flashpoint & prosper! I hope this helps!
He didn't seem to have any issues. Although I'll follow up if he does end up having any.
