Critical Wormhole function on vehicles can break for no apparent reason.

Reviving this thread to say this does still in fact happen. I don't think it was lag; for once, my connection was fine when this happened. It's definitely not because of a paint can; my minisub wasn't painted at all.

I was in a racetrack in the Trench. I tried to warp out, but because I was over some turf grass, it got grumpy and told me it couldn't generate a portal. When I moved onto the shuttle bay plating, which I'm pretty sure should allow beacons, clicking Create wormhole didn't do anything at all! Nor did the similar command in the Ship tab. All the other buttons were fine.
