(Suggestion) Adding Errors to Debug

For example, when you try to add a non-existent variable, or similar, it sends a message like PLAYER x TRIED TO ADD x TO x.

For example if it's an integer variable, and you do /svar set test 123, it sends the failed attempt and what actually was written. Would be helpful for people who have lots of variables and sometimes mess up things, so we can figure the route.
