So I use the Kerbal Attachment System/Kerbal Inventory System mods, and I'm trying to use the connector ports to link two ships' fuel tanks so I can refuel one of them. They will link but fuel transfer doesn't work for some reason--the "in" and "out" buttons don't pop up (They do appear when I select two tanks on one ship, but they all disappear when I select a third tank on a linked ship). I have the R&D unlocked far enough that resource transfer is allowed, and this always used to work fine before 1.2 was released. Is this a known issue or could I be doing something wrong?
Thanks for the help!
