Transfer monster from HI

How do i trasfer a monster if i dont have the app anymore?? I had all monsters except for kamiwyrm…is there any method? Game center id can be useful? Thanks in advance

you cant do it even with HI anymore, it was a temporary thing.

Seriously? I took their advice to wait a bit to see which monsters i should transfer and now its gone? In my opinion there should have been a notification or sth.

I just did it a couple of days ago (after the deadline) and it still worked. 

It did say in HI when the feature was open till. Not that I noticed it first time though.
