At least 50% of the time a previously saved project (from the save disc icon at the top) doesn’t load again. Message says “select a compatible file” . Some of the time closing Lubans and restarting allows the same file to load. Some times I have to simply reload the original stl files and create the project again. I thought it might be the file name format, as If I leave the strange auto generated letters/numbers name it does load back. Frustrating to say the least.
Cheers,
