Annex country: carriers don't work - Anschluss defy: no cores?

So I puppeted Britain to eventually annex them to get hold of their delicious fleet but lo and behold, if I put carrier planes on the carriers they show up as red. The carriers don't work.
I vaguely remember that happened to me before. What gives?

Also, if Austria defies Anschluss (or Chechoslovakia defies Sudentenland) do the claims ever become cores after annexation?

 

[Frozen Yakman]

No idea on the first question, but second one it appears that they will not become cores.

Those carriers have 0 deck space, so they are worthless. It's a known bug when you get carriers through annexing a puppet.

"Captured" carriers, or carriers you own that are from another country, won't let you put aircraft on them, so they're worthless. No idea why that is, it's just like that.
