Exact nature of the problem, where and when it occurs and what you were doing at the time.
Delilah Swansong Syn is attacking a KHK station, at some point it it became unmovable. With Pilor assigned to fly away, IS and OOS it doesnt move. Manually piloting, I cant move forward, backward or shift view. The speed indicators dont move at all as if I'm not giving input.

Where appropriate, additional symptoms, error messages, links to saves *, screenshots and crash dump files (see this Wiki entry).

Immediately afetr posting and teleporting back to it, it can now move. But that didn't fix it before, nor did a reload. So save may or may not work...
