After all this time - inventory bug

I played a lot during launch. Now we are at season 12 and I wanted to see if I would want to play again. On nonladder, I filled my personal stash and my inv with rings/amus. Now about 15 of them are gone.

After 12 seasons. Why isn’t this fixed? Is it fixed on ladder? How are you guys able to play? Have you figured out a way to keep track of what will disappear? How? What do you do when you are going to craft or reroll? What is safe? Half inv? Will some items fix it? Like 15 slots of tp scrolls?
