The Val'kyr is now supposed to have 1 up per zone unless it's already been caught. The respawn rate is pretty fast, possibly as quick as 5 minutes, but it will respawn in one of the other points in the same zone. There are typically 3 spawn locations, so check them all, but don't bother heading to another zone if you don't see one just wait about 5 minutes and check again.
