[1.3.3066] Manned mortars only fire one shell

[Wanderer_joins]

When a faction base has a mortar on its perimeter, the guy manning the mortar only fires one mortar shell. He loads a second one but stops his task short of aiming, he then leaves the mortar and wanders around.

In previous versions he would man the mortar until he couldn't find any shell left.

To reproduce: enter a base with a mortar, the behavior is always the same.

Edit: After investigation: we don't get this bug if we use the classic mortar in the custom difficulty.... weird if the new mortar only changes the radius.

I'm unable to reproduce this in 1.3.3076, please post another report if you still are having this issue.  Thanks for the report!
