I am having pretty much the same issue as jkp993, this cannot be a random issue I am having, I run the program, it works just fine, then while generating Tamriel LODs it gets stuck, and only a moment ago I noticed my computer COMPLETELY FROZE and I had to forcefully restart it, thus I cannot provide any meaningful logs.
The fix you have given me made it work slightly smoother, with the LODGEN not jumping around when generating Level 4 lods to generating Level 8 lods randomly (the logs I have already provided show that).
But what I have noticed in my testing is the fact that LODGEN allocates a lot of memory and uses none of it, sometimes having bursts of sudden memory usage but in general not using any memory. I used the Performance Tracker program that's in windows to track this, it's more detailed for this stuff than Task Manager. I would provide a printscreen screenshot, but sadly, printscreen doesn't work when my computer is completely frozen. Under the "Confirmed" memory, which summarizes all the allocated memory, all 5 windows allocate more than 3GB of RAM eventually, with some going as high as 9GB of RAM, but only using around 1 to 100 MB of it in random bursts. The allocated memory always exceeds actual memory available.
