sketch undo corrupts expressions

[steve123]

If I create a sketch and set some constraints where the constraints use expressions (for instance, a spreadsheet), if I execute an Undo at some point, the expressions are corrupted.

Werner has very recently improved the undo function following faulty behaviour with a sketch and corrupted expressions. You may search the forum or just wait a few days.
