If you find any bugs or it just doesn't work for your online games at all, let me know but most of the time it's probably just scratch's servers down... The "Cloud" variables are not actually cloud and are meant to show where the cloud variables are meant to go and where the normal Variables are meant to go!!
The invisible character is what separates the data in the cloud variable, if the dataset doesn't have this invisible character then my engine will automatically put it back but not exactly...
