The error, from the few tests I have done, doesn't seem to make a bad sector, but weird stuff may happen, I don't know. UPDATE: This project may occasionally freeze; I think I have fixed the issue. If it freezes, report it IMMEDIATELY. I swapped from my old broken drawing system to an experimental single script one that uses data from the clones only.
What's New in 2.6.4: Minor fixes to beacon types and the renderer. Now everything should work properly. Note: Errors now may cause islands. It is recommended that you use numbers that don't throw errors.
