Ballista Triremire Projectile

Hello,
With the latest patch, greek ballista triremires can reach over 100 range. But the projectiles probably has a self remove time after creation, which ends before the ballista reaches the target in long ranges. So the projectile simply disappear in the mid air.
Any plans to increase projectile speed or increase its life time? Not a huge bug but its annoying when you send ships to attack a distant fort and 0 damage unless you push them forward a bit.

Thanks
