In Aristeia, I noticed that Support only works for the first rearm (and that's only if it was not already on field, ie. it warped in to rearm me).
Any subsequent attempts at rearming result in the support ship flying past me and keep going in the same direction forever. The countdown for when it'll dock stays stuck at 00:26.
For whatever it's worth, I'm specifically noticing this after using a checkpoint, and I don't know if it happens before the checkpoint or by progressing through the mission normally.
My FSO build is November 11's Nightly (2283295).
