AI Controller LineOfSightTo() stops working - tips welcome

Alright, thanks for posting your code, I don’t see a problem with what you currently have. But I have an idea that could show you where the problem is, are you by any chance using an editor which can use Breakpoints? If so, please put a breakpoint on the function it calls, that would be AAIController::LineOfSightTo() and post an image of where it is returning false.
