PC: The amount of items that I can transfer into a storage crate is no longer accurate (this is an issue for the slider UI element as well). This only occurs on my end, my friends don’t have this issue when using the same crates in CO-OP. It is not specific to any storage crate, it applies to all of them.
UPDATE: Taking all instances of the item out of the storage crate, then putting all of it back in at once, and then taking the original amount out again rectifies the issue.
