I would like to make a saving system with cloud variables. I have tried before, and I have tried with lists. I have even tried using a cloud variable that never reset, it just followed whatever the value was the last time it was updated. Each of these times, the list and/or the variable would reset when I pressed the restart button. I heard that the variables were saved to the scratch servers, however, they seem to reset to the last time I pressed the “save” button in the editor. Can someone help me with this? https://scratch.mit.edu/projects/729960615/

I see none of your variables in the project being “cloud variables”. You have to select cloud variable to get that to work.
If you want to incorporate a list into a cloud variable, you might want to try joining numbers together such as

(join (join (item (1) of [list v] :: list) [etc]) [etc])

You have to make sure that you use numbers, as cloud variables cant save other stuff.

Ah yes I have tried that on other games as experiments, however, whenever I reload the page, all cloud variables and lists just reset to what they were before
