My friends and I were all different gravities, but when we went through a portal, we all appeared down to each other, even though we all saw ourselves as anything but down. To circumvent this, we all set ourselves down, and then back to the gravity facing we were before which fixed it, but it was a tedious task. To recreate this, get two accounts on a server with the mod installed, set yourselves as a gravity other than down, and then both go through a portal.
