Hi, thanks for taking the time to let me know about this.

It looks like a bug with the new range rendering functionality. I'll get started on a fix. In the meantime, you should be able to bypass it by disabling the "Draw Range" mod option in per-player settings.

This should be fixed in the new version. Let me know if you still have trouble after updating.
