Last night I found 4 of 5 probe before I stumbled upon an enemy base. I destroyed the base even though I was not instructed to at that time. After spending a good hour searching for the fifth probe, I finally found it.
To my surprise, I now had a third part of the mission to do. Guess what that was , Destroy the Enemy Base. So, I travel back to that asteroid but didn't find a respawned base.
I sent in a bug report, and I sent a note to GM.
Today comes along and I reeneter the system, hoping to search for the missing base and destroy it. Instead, I have to do the entire mission over.
My Advise from playing a lot of other MMO, respawning os very nice to have sometimes. In my case, my ship shouldn"t really be in that sector just yet, but I managed to kill everything on my own. It took a long time though. Please make this better for the next player that comes by.
