The real problem isn't the loss of mythical creatures, we can just merge current creatures into new ones. The problem is the flying treasure chests D: I have never seen any lifeform that could be used as a base for breeding new flying treasurechests. Dman you M. Critter, thanks to you I couldn't become an adventurer :(
