Did something change with the Core Backpack? I'm having problems now

So basically my problem is, adding a tool to a player’s backpack using a script is now causing a tool button to pop up in the backpack with its number being 0.

The tool button is unresponsive, you can’t select it again if you deselect it.
I have tools being auto selected when a player starts a minigame. Neither clicking the button or pressing the associated key works now.

This is causing a lot of game breaking problems at the moment

It now appears to be fixed!

This bug is back again!

It actually doesn’t seem to matter if the tools are added by scripts.
It appears the fourth tool added to your backpack breaks the backpack core GUI.

This isn’t place specific to my game, I’ve seen it happening in many places.
I’m hoping someone can fix this, because I’m not lying when I say this is very game breaking for me.

A handful of players in my pilgrim game reported this as an infrequent occurrence. I’ve only personally experienced this in Play Solo mode (95% of the time) with a smaller screen, before I got the 1080p monitor. Perhaps it has to do with screen resolution & messed up backpack code? Hmm

I’m currently running on 1366x768 if this is helpful information.

This should not be a problem with the new backpack, released today!
Please let me know if you see it again
