Failed to call hook 'CanUpgrade' on plugin 'BetterTC v1.5.93

There are a lot of bugs. I suspect they occur when a player doesn't have permission to play but clicks the buttons in the cabinet.

Hi! If a player doesn't have permissions, the upgrade action won't be performed.

I assume this happens when another plugin that also uses the CanUpgrade hook runs it. Could you check if any other plugins use it? (You can do this with a global search across all your plugins using Visual Studio.)

I suspect another plugin is interfering.

Did I understand correctly that I need to look for CanUpgrade in all my installed plugins?
