Telesci needs to be "primed" before it can receive critters

[Sov]

If you try to receive a critter through the teleporter from the station / debris field (zombies, fermids, etc) it will not work at first. To make it work you seem to need to "prime" the teleporter first. You just open a portal to somewhere safe-ish - walk through it-and return. After doing that any subsequent attemps to bring in critters works fine.



This may also be true for receiving humans too, but I didn't have any to test it with.
