Vending items dropped out of back
Vending Machines Bug? spit payment out the back
This doesn't happen every time, but it's happened enough times that it's getting annoying losing stacks of valuable stuff when people buy from my machines. Sometimes instead of storing the payment items in the machine, it drops out the backside onto the floor. I am not standing behind the machine 24/7 so the items are despawning before I can retrieve them.

Is there some workaround for this? Is it tied into the triangle foundation issue? I've never had one break while working on the base like some people have reported, just this issue where payment items are dropping out the back of the machine and despawning.
When I buy something from the player's vending machine, if I buy in bulk, the item will fall off the vending machine. I have installed StackSizeControlller.

I don't know what went wrong.

Sorry my English is poor, I hope you can understand. XD
Items can sometimes get dropped on the ground if the game tries to put them into a full container.  Perhaps this?  Is it possible the player and/or vending machine had a full inventory?
Vending machine is not full,and I can put the currency into it,  but if I buy in bulk, the currency will fall off the vending machine.

same issue here.

may be you can update stacksizecontrol
Did this fix the issue for you?

Had same issue.

Jpipes was the problem. After deactivating Jpipes no currency item dropt out of the vending machines.
