Omg I never got notified for this post, I'm so sorry omfg :Peepo_dead_wasted: I am aware of this issue, for me on my end my solution was just to not move items inside chests, it was easier to deal with when it's still in your inventory before you store it anyway. Editing tuning values like this something that can solve the issue potentially. At scale though, you would have this issue eventually anyway though; for instance, if your stack had 100,000 of an item (somehow), you would find you would only be able to move 999 of them at a time; this code would have to be applied to stack sizes of all kinds to mitigate the issue (which isn't necessarily an issue, but still)
