Warp point closing error?

[zen.]

Has anyone ever had problems with multiple computer-controlled Close Warp Point ships converging and crashing the game? I'm assuming that they are all trying to close a warp point that was closed when the first ship got there.

Background (for those who want more details): A crash kept occuring on the Romulans' turn. I tracked it down to three or so Close Warp Point ships converging on one sector. I couldn't even avert it by controlling them because the order had already been given and was being executed. The ONLY way I managed to kill them was by controlling the nearby Sallega empire who happened to have an attack ship in the system. I doubt I'll be as lucky next time, though...has anyone ever had this happen to them? I'm using the latest Romulan AI and have never seen it happen before with any other race; was this just a fluke?

TIA,
