Thanks for the code contribution. FYI - I no longer work for Unity and don't think anyone is monitoring this repository, so you might want to check in on other channels to see if someone can merge your change (or possibly this project should be archived if no one there is going to maintain it moving forward).

I'll add more fixes to my fork https://github.com/StCost/AutoLOD
