Short description of error
crash when saving this file
Exact steps for others to reproduce the error
open the file, try to save it, crash.
ive found that if you turn off the "GPencil" object visibility from the outliner, it wont crash and it will save, but still crashes if you turn visibility off to the modifiers or layers.
