(svn r13724) [NoAI] -Fix r13723: in this modern world with all those checks and warnings GCC can give when ever I not ask him to, it fails to see the simplest of all, 'if (cargo_id == cargo_id)'.. makes you wonder, doesn't it? Well, such is life, wondering wondering wandering .. Status Quo, Yeah! Oh yeah, what was I doing ... ah, yes: don't compare one variable with itself, it is always true.. Obiwan by Yexo. (Yexo)
