## Bugs

- [3D View](#3d-view): Random Type Box 1 and Fixed Type Box objects aren't rendered correctly
- [3D View](#3d-view): Some objects are only partially loaded (they consist of several seperate models)
  - Forest Switch
  - Laser Fence
  - Forest Laser
  - Switch (none door)
  - Energy Barrier
- [Script Object Code](#script-object-code): Make sure data segments are referenced by an instruction with an offset before the segment's offset
- [Script Object Code](#script-object-code): Detect code that is both unused and incorrect and reinterpret it as data (this avoids loading and then saving the quest incorrectly)
- [Area Selection](#area-selection): Lost heart breaker/phantasmal world 4 overwrite area 16 to have both towers
- [Area Selection](#area-selection): Show areas that are referenced from .dat but not from script (test with Point of Disaster (709))
- [Load Quest](#load-quest): Can't parse quest 4
- [Load Quest](#load-quest): Can't parse quest 125 White Day
