I've tried to use tall shelf's and skips but they can only store 2 stacks of items no matter the weight which makes them useless

Well, I fixed it by changing the location of the mods. At first I turned off most of the mods, and then turned on 2-3 mods. I found the problem with the elimination method. If you have a fridge mod (RimFridge) installed, put it above this mod and sort the mods. Helped me.

thanks man!
