I am getting the same problem.
It would be appreciated if someone could please report the bug to Roblox. I would do it myself but I don’t have the right ranking or ‘trust level’ on the devforum to do so.
I just started getting this error.
I’ve been having trouble with this bug ever since a few days ago. It would be nice if this gets fixed as soon as possible.
This issue might be related to the use of “increment” to change a value in leaderstats. As an alternative, using a “+=“ syntax with a “set” command may resolve the issue.
