Parallel Universe on Otyugh with Momentum results in something different

[helium]

The opponent had a Otyugh with Momentum added. As I cloned it with Parallel Universe I got an Otyugh with the same states except the  ability wasn't devour for one gravity quantum but instead momentum for one gravity quantum (which additionally was a useless ability as it already had momentum).

I don't even need to see the picture. o-o This glitch has been complained about many times before. Whenever you PU a creature with Momentum attached to it, the new creature's ability will ALWAYS be replaced with Momentum.

I vouch for Jellyfish. I didn't need to see the picture either. If a creature has momentum, it doesn't matter what other abilities it has; if you PU it or mutate it, the new creature will have momentum and nothing else, every time.

I hate that it does this, but now have my deck changed accordingly to the 'bug', if it even is one.
