Thinking about buying, 2-3 questions tho

[Heureka]

Its a limit of how many props (meshes), not blocks, you can have in a chunk.

See this.

It was a purposeful addition (Though I do feel like it should be recording vertical segments separately which would allow more to be placed in a single chunk as long as at different y levels etc).

It is mostly a client-side performance consideration yes, and whilst it may be strict right now, it can easily be lifted to a higher value.

It is effectively, to stop people making a big block of 100,000 complex mesh blocks that would grind everyones computer to a halt when they get close.
