I got a jump drive ether drake despite the fact that my ships transitioned to the psi-jump drive.It might be the case that the Ether Drake can't be changed from the original owner's FTL type. Or it might not be the case. The devs will know which, and on that basis will also know if this is a jump drive-related bug or just something to change.
I was a wee bit disappointed because the hatchling is awesome.
But attacking weak empires with the drake is actually quite a bit of fun.
