The player boundaries have been changed since 0.8.0. Does this still happen in the latest 0.10.0 release?

v0.10.0 I just checked around the waterfall and pretty much everywhere else on the map thinking I had to find the fake elf ears instead of craft them. the only spot I didn't go through every square inch was the gap between the rocks since I read the mesh was a temporary and anyone that goes there never gets out.
Great game by the way ^^ can't wait to see more content and that hint of another Village in the Forest.
