Troll Catapult Bug

[myself]

So I have noticed an annoying bug about the troll catapult in my version of the game. If you play a custom battle (or a campaign battle) on huge unit scale, one out of the four catapults you have will not move. So it will get unlimited range, which is a little annoying (especially if you are fighting against mordor). Has anyone else experienced this bug? Note that this bug only happens in huge unit scale (for me at least).

I'm also using huge unit scale but this bug does not happen to me. At least I've never seen the having a problem with them (I don't play with Mordor).
