[Bug]: After updating the mod from a version to a higher one (currently from 1.21.4->.5), chunks that has entities inside blocks (like painting behind a pot, or (my main problem) armorstands modified with the "Armos Poser" mod) can't load correctly!

1.21.5

What is the problem?

So, I've contacted the Armor Poser mod creators about this, and it turned out the problem of the armorstands losing the items was not because of their mod, but because of the Connectible Chains mod. Armorstands had items inside blocks lost the items in chunks that had leads or chains from the mod. After removing the mod from the modpack, loading the save without it and then updating the whole save to the newer version (without the C.C.) everything was fine (Armorstands had the items and the painting behind the pot didn't break), so I'm pretty sure it's on C.C.

This whole thing only happened when I updated the mod (when I don't update the mod, they are perfectly fine with each other). It happened before, but there I was able to fix the Armorstands, now it would have been so much work to do, that's why I happened to land here.

To recreate the problem: In 1.21.4 create a world with hanging chains/leads and custom armor stands (the be sure do it with Armor Poser), then update the whole world and the mods to 1.21.5.

1.21.4 with C.C. and Armor poser. 1.21.5 with C.C. and Armor poser.
