Just to add my sixpence: my world also has a relatively large village which we've built from scratch, and it's in that area we mostly play.
That seems to feature in other people's comments.
However, the village is not as populated as it's previously been, and it's been at the same size for quite some time, whereas we're only experiencing this issue for the past few days, with it only becoming unplayable last night.
Prior to this, though, we did have a lot of creatures despawning.
