So, shortly after an untamed wolf is spawned in, with-in a very short time after minutes it often spawns out. Even if I place it in a boat and/or I get in with it, it will despawn the same fast rate, after a very short time latter. I've never seen any other neutral and/or pieceful mob despawn this fast, this consistantly. Definitely is not just bad luck on my end.
Unless I already have bones or a name tag in my inventory, the wolf 99% of the time will despawn before I can get bones or a name tag in time, regardless if its a how short of a travel it is to any chest I have with either items in them.
please, don't have untamed wolves despawn as quickly like they currently do; no way this behavior is intended or that I am just unlucky, its way too consistant that out of every tamable mob, neutral mob, and/or pieceful mob the untamed wolf is much more likely to get despawned first or very close to it. regardless of if it just spawned in or how close and/or further away it and other mobs are, it seems to have the short straw in getting despawned consitantly before most or all others. on every playthough I've done on the more recent updates, the behavor seems consistant, that the game prefers to despawn untamed wolves. seems the game has a bias twords them.
Are you able to record and attach a video demonstrating this behavior? How many blocks (on average) are you standing away from the wolves? What is your current simulation distance set to?
