Ah awesome, thanks! :D
This should fix my problems.
Edit:
Btw knowing all this, my problem does look like a bug. I have 3 ships, and they get stuck like this often, even though the game should have two sectors loaded, (nowhere near the 500, nor the 5) I exit one and they get stuck, or maybe one follows the other doesn't. If I go back it gates immediately to the new system.
Anyways with Sector Manager, and changing the update interval , now mining at least seems to work, so thanks again.
