Access violation that only occurs when attempting to produce Grass Lods

[Superjosh58]

When using Dyndolod normally, I have no issues. However, I decided to attempt to generate a grass cache and when attempting to use dyndolod afterwards (texgen worked as expected with grass billboards), I get this error.

What is unique about my grass cache or generating grass lod that means this error appears, but never does otherwise?
