Disappearing data

[Léon]

Thank you, SuperTech, for your effort to solve this problem.

Today again: document "Energy consumption" is open. Cloud service is off.

I drink 2 cups of tea and return to the computer.

The number of "Year consumption" is replaced by a 'w' (again). No possibility to go back one step.

Close the document and don't save the changes. The only way out.

Start again filling in the changes.
