Sliced trees and unblended biomes

Plugin version: EWG 8.0.2

Issue: When a new world is generated using EWG, some of the trees that are generated seem to be sliced in half. It seems to be random, with no link to biomes or any other factor causing this issue. I've also had an issue with biomes not blending properly. I saw half of a village, while the other half was sliced off and instead a large, high-up snow biome. Any ideas?
