I am running into a problem with some of my TGs stopping midway through an order. I noticed the problem when a TG did not reach a rendevous. I looked around for the TG, and found it several systems back. It claimed to be moving at full speed, but there was no motion "tail", and several weeks later it was still in the exact same spot. I can sometimes get the TGs to move by changing the commanded speed, or by clearing and reissuing the orders. I have tried splitting the ships from the TG, and issuing the orders again, but that does not always seem to work either.
I am running version 5. 3. I am also getting one or two "Error in ExecuteOrders, error 6" errors every turn that may or may not be related. I do not have the DB password, so havent been hacking the DB. However, I have had a couple of times when Aurora basically locked up (turn still running after several hours), where I have kill the Aurora processes and restarted. This seems to have worked, but there is no telling what that sort of thing might do to the DB.
Any ideas on how I can get my TGs to behave?
