I cannot undo actions after saving a file. No matter whether it’s autosave or manual save. I think it’s not typical behaviour for sketchup. I haven’t noticed it before. It happens to every file, not any particular one.
Thoroughly speaking: after I save the file and click Edit-Undo, it always shows “undo properties” but it doesn’t change anything.
I am so frustrated about that ;(
Perhaps I installed a plugin that messed with the program? But I’m unable to check that. I have over 100 plugins installed and I cannot tell when it happened.
