Foliage Interaction/Harvesting

In 3 packed version tests foliage DOES remove but doing so seems to create loss of visibility in foilage in the same landscape tile.

Visibility changes in such a way it suggests lods are the issue. Ie some untouched foliage becomes invisible when getting close to.
some appears if you stabd 1000 units from it but not if you close to 600 units of less

Ive wasted 2 Working days on this trying to isolate.
i NEED this resolved asap as i have a pressing deadline.

im not a c coder and would rather this updated by the plugin and marketplace creator so it works as meant to, than make dynamic instance buffer changes myself as per poster above. I have 100,000 tress bushes and plants and do not want sudden game thead surges .
ie if pack creattor truly has packadged games that dont need a dynamic buffer i woukd orefer that solution or a solutuon that does not pollute game thread
