Hand Teleporter Portals Broken

[Archenteron]

Twice now, I have gone through a hand teleporter portal, misfired into space (as per usual), and then been unable to open and re-enter a portal via throwing stuff or using a fire extinguisher. I'd open the portal, jet away, jet back, and be unable to enter the portal. The first time, I was a Captain and thought it was something related to my armor or the disk or my shoes functioning as magboots and keeping me still, but the second time (tonight), I was the RD and had nothing that would seem to have fucked with my portal-using.

Please fix this (or remove the misfire chance for non-random hand portals)
