I have Realms Plus server and the only members are myself and my daughter. In the past few days we have had pets and villagers go missing. I have mostly been alone on the realm and we have been together whenever she joins (hence it is impossible this was caused by a player or mobs, aside from possibly the single missing sheep which could conceivably have been caught in a creeper explosion). None of the missing pets were named but most had been tamed. World was started locally and uploaded from PS4 version (on PS5) to realms plus. Daughter logs in on the playstation, I have been playing on PC via launcher since the upload to realms.

More detail:
First I get back from a long voyage and I notice one of her cat is walking around (they had all been sitting). That same evening (maybe before, maybe after) our nearest village (a few hundred blocks away) was missing all of it's villagers, golems and cats. Other villages we have found in the vicinity seem unaffected. The following day we notice her other (2-3) cats have vanished, as has my only cat. This may have been the case already the evening before, I might not have noticed. One sheep is also missing from within a fence. I looked to see if this was a known bug but could only find reports from a few years ago, supposedly resolved. The cat that was walking around remained, as does a white horse I brought home the evening before (tamed by her), and two black ones (one tamed by me, the other untamed I think). After this we bring a dog and name him and for the next two days I have repeatedly checked to see if all animals are present and all has been good. Tonight I just got back from another voyage (where I had mapped out a 2-3 size 3 maps, mostly boating, as I had done on the first journey) and the two black horses are gone, the leads still tied to the fenceposts (see screenshots), one was within a fence as well. The two missing horses were picked up and brought to base at the same time (but on a different trip from the white one still remaining). The world is about a week old. No farms or large number of entities.

Please fix this, or let us know how to avoid it. Mapping is one of my minecraft loves and so would hate for that (or boat trips) to be the reason for this. It really makes it hard to invest time or effort (or money - the Realms is still a trial sub) to not be able to raise animals or build up villagers for trading.
