How do I transfer crew back to the XR2 after transfering it to the Deepstar or the Interplanetary Carrier Vessel? Can't find a way to do this in the manuals. How do I transfer people to the landers?
Keep in mind that Dan Steph's UMMU is not fully compatible with Orbiter 2016. You can expect a CTD whenever you try to go to first person view in one of the UMMUs and/or weird behavior if you try to place them on the new 3d terrain of the planets that have it.
Seems to be working ok for space-only, external view-only.
