Lathe targeting prioritizes land cannons regardless of lathe settings

[strigvir]

What category do those cannons belong to anyway?

Apparently, these cannons are called "Ticon Defence" and are targeted by Lathe regardless of target setting. Fix pls.

I've added them to the "Structures" group for the next build.

V, while you are at this, could you please state what's in each group?
Thanks
