So, I should have mentioned this by now, but I have an idea for what causes most of the bugs in my world, and I would like it to be examined.

I have submitted almost 10+ bug reports already, all for the same world in the same scenario.

However, I have a hypothesis.

When Mojang adds title updates, it often modifies seeds of older worlds... However, with the newer system, it allows players to keep their old chunks without losing any builds. This will cause landscape and biomes to overlap (hence raining in snow biomes, etc.)

Now, I am suspicious that the seed changes, but the world keeps the old chunks to preserve builds, I find that might be the source of many of the bugs I am finding. (I have a LOT of these preserved chunks because my world has existed through numerous title updates over the course of years time)

My world started a long time ago, almost 3 years ago on the Xbox One Edition. I kept the same world (which is a survival world/achievements enabled), and I wonder: if I travel outside to the 'newer current world seed chunks' then I might not have the same bugs.

Like an example would be my villagers wont breed in my old-world preserved chunks, but if I travel outside to the unexplored chunks, new villagers might breed there. That is just an example, but I am suspicious that this system might be the cause for so many bugs that I personally am experiencing, and maybe different from others.
