We're trying to collect wyvern eggs. We have an argie and a Cryo goddess. When we pick up the egg on the argie, the egg is in inventory when we finally lose aggro. When we pick up an egg and fly off on a cryo goddess, the egg vanishes. The wyverns still behave like we've taken an egg, but there is no egg in inventory, its just GONE. It wasn't dropped, or accidentally eaten or not grabbed. It ONLY happens when riding a cryo goddess. all other flyers it works fine.
