I was Pvp’ing with someone and somehow my last Ark , wasn’t there at the end, i double checked to see if he was still in there and he was, not to sure but has it happened to anyone else, or is it indeed a bug?
It’s quite likely one of your earlier arks used a move like devour or throw (or bloodmagic, or a bunch of others) that sacrificed that last ark without you noticing. Megalorex is a really terrible one for this, as he can’t be controlled, so he can just go killing off your team with devour and there’s nothing you can do about it.
oh so me using Nilomoths devour, would of taken my last monster up?
Must of not read the description properly!
My bad!
That’ll do it 
Thats why i prefer risky heal
