Planes stuck at de-ice pad

I have to look into this further, but I have planes stuck in front of my de ice pads with a no valid path to runway error. I’ll file a bug report if I can reproduce it later.

The planes were queued up to use the de-icer, but the temps got above freezing while they were in line and the de icers closed… shown by my 6.9C temp and no de ice trucks at the pads. I think this caused them to infinitely wait until the de ice pad opens again.
