I just followed this tutorial: https://adventurecreator.org/tutorials/custom-save-game-labels
Everything seems to be working okay accept the game only saves a single slot. Each new save overrides the previous save.
When you try to load a save, there is also only the single save slot available.
I did not know what to do with the Retro Save Games unitypackage. I tried to open it once with Unity and it caused a bunch of script errors in my project.

When using the Save: Save or load Action to manually save the game, the slot used is determined by the variable assigned in the Integer variable field. Is this being correctly set?
The tutorial sets the "Save slot index" variable by referring to the ClickSave ActionList's "Slot index" Integer parameter, which should be set automatically to the slot number, because its been assigned in the SavesList element.
Check that this is all the case - if you can share screenshots, I'll take a look as well.
I'm not sure but I noticed that the part I circled in red was different in my version from the tutorial. Could that be what is wrong?


The use of a custom save label shouldn't factor in - though I'd recommend unchecking it until the issue is resolved.
The thing to look at is the "Save slot index" variable - what is it being set to at runtime?
During gameplay when I try to save, the "Save slot index" variable starts at 0, then after saving changes to 1, then stays stuck at 1 where it is overriding itself.
Are you able to choose from multiple slots to save in, and "Save slot index" remains at 1 no matter which slot is clicked?
The "Save slot index" variable should only be set within the properties of the SavesList element that contains the save slots - is this the case, and what are its full properties?
