The messages actually make a lot of sense if you understand them. That understanding comes from the fact that they're not telling you what is wrong, but instead telling you how to fix what is wrong in most cases.
This particular one tells me that the weapon owner has a problem and then gives off what it expects to find but isn't finding.
There is likely a weapon with a range trying to target one's self, or a self targetted weapon has a range or constraint which makes it impossible to target itself. Or possibly a weapon trying to fire in a direction it's not pointed at.
