Spearmen fighting "through" wooden pallisade

I noticed if I click on my Caucasian spearmen to throw their javelins over the palisade at the adjacent defending units, my spearmen move right up to the palisade and the melee symbol appears - as if they are actually fighting the enemy unit. At this point I cancelled their orders and withdrew them in case it caused some other unintended effects.

Javelinmen are getting a range upgrade, which hopefully will fix this.

good to know it's beeing fixed, had a lot of spearmen advancing so far that they were in melee and thus fought in melee instead. :/
