Thanks! Is this based on the logic how it worked before 99a609b4233bc0fab345190db859b9636dc15f6d or how were those changes made?

Ok I just cross-referenced it with the commit and it seems that there is an additional change in the PriceRestrictionModule and the SignSticker (I commented those on the commit), could you fix those too? :) (As well as revert the array syntax change)

The one in PriceRestrictionModule is not missing https://github.com/ChestShop-authors/ChestShop-3/blob/16515aaba442dd3a38d8baa10a719513424dc7a0/src/main/java/com/Acrobot/ChestShop/Listeners/Modules/PriceRestrictionModule.java#L117

I think we should fix it too: https://github.com/ChestShop-authors/ChestShop-3/blob/e40b5567b87617c432e65c84f9d1a03d4d9ae81b/src/main/java/com/Acrobot/ChestShop/Listeners/Block/SignCreate.java#L34

You are right, not sure how I missed that.
