ERROR : Error in lua for scenes and events help

My ver seems to be doing this often, it doesn’t happen after a reboot it just shows up and my scenes stop working, not sure why but my unit has been up for 2 + days then all of a sudden it shows this

never seen this message without a luup reload. It is strange since the scenes and watches are loaded and checked during the initial loading of the program. I don’t know if they are ever checked again afterwards.
