Yep. Here I am, circumnavigating the galaxy, and my cargohold full of repair limpets, is now a cargohold full of nothing. Just from switching between EDH and EDO, and back again. Of course, I could synthesize some, but why should I waste my materials synthing something I already had, and that the game just decided to delete for no apparent reason other than EDO is a broken mess that is messing with everything.
