foldit.exe repeatedly and reproducibly crashes as follows.
when a puzzle has been worked on and solutions were saved and shared, and the puzzle is then reposted, the earlier saved solutions are still present on the PC.
when trying to upload these saved solutions from the earlier version, the program immediately crashes and needs to be restarted.
When loading these old solutions, then re-saving them, the solutions can be shared without a problem.
This could be fixed.
Observed, for example, in puzzle 907B.
edit: not sure if this was deleted intentionally, if so, sorry for reposting, but I cannot find the original post anymore...
