[1.0.52] Crash when generating new distant town mesh

[Shidan]

Been getting reports from a user running a mod of mine that has been experiencing frequent crashes. Having taken a look at their logs, it appears to be happening when the game tries to generate a new distant mesh for a town that didn't already exist in vanilla. Something I've been hearing numerous cases from other modders as well.

Unsure if it's a permissions issue, though it sounds plausible since those meshes are stored in the installation folder, which if in Program Files has been known to cause such problems. Waiting to hear back from the user where their game is installed.

Dump attached below. Let me know if you need any more information or files, and I will try to get them.
