Perspective grid automatically resets to default
I use the perspective grid tool to label 3D illustrations. I have been having the issue recently where; when I open an existing file that was built using a customized 3-point perspective grid, the grid has reset to the default 2-point perspective grid. The primary issue is that my perspective text is displaced. If I "view>perspective grid>three point perspective>my saved custom grid", the perspective grid is expanded and stuck in the default 2 point perspective projection.
I have spent hours re-doing the work and each time the issue reoccurs when I open the file the next time.
PLEASE HELP!
