Archery No Skill Gain When Firing From Bridges

Playing on a WU server.  I received no skill gain when shooting arrows from a large cart parked on a bridge.

Did you receive skillgain when not on the bridge? What was your skill? what were you shooting at? did you hit? did you hurt it?

I was getting continual skill gain shooting hardened ven hell scorps until I stopped on the bridge.  It was at night, 60 archery, 55 longbow shooting longbow.  The moment I left the bridge, skill gain ticked again.  Everything else was the same.  I was hitting the scorp from the bridge, just not getting a single tick of skill.
