Hey there. I was doing some tests with the mod to figure out how it worked. One thing I noticed, was that if you recover a vessel that has frozen kerbals in it, those kerbals are not added back to your crew list at the end of the mission. I was using the planetary base module to freeze them. DeepFreeze seems to still recognize the existence of the kerbals though, upon launching a new vessel and checking the deepfreeze tab, it showed the missing kerbals, albeit with no vessel assigned to them making them floating around in whatever void they have fallen into. This WAS in version 0.24 though, so it might be fixed in 0.25, but I didn't see anything about that in the known issues or change-log so I don't know. Thanks!
