How to fix message system error

I’m making a game, and in it there’s a message that is sent to multiple objects. The problem though, is that sometimes it never reaches some of the objects, causing an error in the game. Does anyone know how to fix this? I can post my game if needed
here’s a picture to show what I’m talking about


I’ve found that when toggling the visibility of an object, you have to shut off the visibility actuator that is setting the incorrect state. For example:

Setting visible:
Turn off invibility actuator
Turn on visbility actuator

Setting invisible:
Turn off visibility actuator
Turn on invisibility actuator

Oh, thanks…helps get that annoying kink out
