I had 4 foxes that I bred myself, and they trusted me up until recently. They no longer trust me, and run away from me when I approach them. I am playing on a Realms 2 player subscription. The foxes are named. Two of them are arctic foxes, and two are red. I have resource packs enabled (only textures are changed). Cheats have never been enabled in the world.

I haven't been paying much attention to the foxes over the last few days, and it's possible that the issue may have been present before today (I noticed it today). I suspect that the Foxes may have lost their trust when the world was uploaded to the Realms server (I purchased the server two or three days ago, and uploaded an existing world to the server rather than creating a new world).

Edit: It turns out that on other worlds when moving them between a dedicated server and/or realm foxes have lost trust then as well. I haven't checked in a while but from what I recall I think my wolves lost trust too (almost as if my player uuid changed or something). My friend was playing on the world with me and from what I remember his pets did not lose trust. So, to sum it up, my pets appear to lose trust in me when I move a world between a server, realm, or my local computer, and it does not happen to my friend.
