Artillery is forking awsome for us! The problem is with turetts which are using the vanilla or moded cannon shells, in the vanilla game you can only shoot them from the tanks, but with mods you can use canon turrets as well. The problem comes when the turet starts to rank up it gain more fireing range that the max travel renge of the shell (if i am right the original lifetime of a cannon shell is 34 tiles and this is the basic fireing range of the cannon turrets in all mods i could find) . After a canopn shell travelled the maximum range it automaticly explodes, so if my turet is ranked (so the renge of it is more then 34) theres a lof of cases when they just shoot the ground because the turret can see the target but the shell can't reach them.
Btw... I forgot to say thank you for this great mod! We are having a lot of fun with it!
