So, I was messing around a bit in creative, spawned in a dragon boss for fun, i had one ironbelly wyvern and one ironbelly dragon which i had tamed a while ago, i killed the dragon boss i had spawned with the creative gun, but both the wyvern and dragon both kept attacking it, i put my dragon on passive and moved it a good distance away, but the wyvern was the odd part, i was telling it to stop via whistle commands, but she wouldn't stop flying around the corpse, even when i managed to knock her out, and move her about... 20 foundations away, when she woke up she just went right back to it: flying mindlessly around the corpse, alongside the fact that i couldn't select the ride option there was no way to make her stop.
