Bug or Feature Physics Question

I have been struggling to build a station around Minmus and have left several modules in orbit.  I just launched a large tug that works and have started assembly.  The tug has two nervs sticking out the side and until construction is more complete must pull.  One of the modules had deployed gigantors.  When the tug docked one of the engines pointed at a gigantor, I ignored this.  I set up a maneuver node to take the section to the existing station and fired my engines when the time was right and swerved.  It took a couple of attempts before I noticed the gigantor and wondered if it was the problem.  I retracted it and the burn went off without a hitch.  I know this behavior is expected in reality, but is it intended in game?

Yes, thrust can be blocked by other parts. The checking is pretty simplistic, so there are times when thrust should get blocked but doesn't.

Thanks much, I wish I had known a little sooner
