I have found 2 possibly unrelated possibly already known bugs. the first is that (for me at least) the kerbal inventory only has a volume of 1L meaning they can't even hold a drill (3L). I poked around the confg and found where it looks like it sets the kerbal's inventory, when i found it it was set to 300. i went ahead and tacked on 2 more zeros to see if that changed anything, it did not.
the second may or may not be a bug but none of the command or habitation parts have inventorys to begin with.
any help would be appreciated.
