<![CDATA[X ERROR - unsupported types for __and__: 'function', 'int']]>I keep receiving "X ERROR - unsupported types for _ and _: 'function', 'int' " on my M5Fire for the following code. Sometimes it happens right away, other times it works flawlessly for a little while and then I get the error. Can anyone help with this?
