What's problem you are encountering?
if I store a list in a transient variable it is slower to read/write to
What have you tried that didn't work?
disabling transient and manually emptying when I save project
Post a project example, link, or screenshot:
so in my project I generate the sprites using pen and save them to a list of all sprite pictures. I have it all on a event.
<Image would be here. but despite above I cannot post media>
It noticablly pauses at the insertion into list step. IDK why this is. but I just chose to manually clear the "cache" for the sprite
