I separated a stack of 10 and it wont go back together. Its like they are suddenly different items. When i crafted bandages the same thing happened where just 1 wouldnt stack with the rest. This happens in both my inventory and inside chests. No, it wasnt food becoming stale its been arrows, bandages, bug parts, etc. Ive tried taking a partial stack and saying deposit all into a chest on the other partial stack, still doesnt work. Clicking and placing the partial stacks forcibly on each other also doesnt work they just swap spaces. Even depositing 1 at a time wont allow them to go into the same stack. It either starts a new stack or if the inventory is full is grayed out entirely indicating theres no room even though there are partial stacks of the item in the container.
