Summary0011011: Catapult/Ballista projectile falls z-level through solid floor
DescriptionI constructed 4 catapults on a level (z-0) that fire projectiles 0000009:0000007 tiles against a wall with a channeled floor. The level below (z-1) contains both a solid (chalk) floor (which collect 2 catapults ammo) and a microcline floor (which collect 2 catapults ammo, made during troubleshooting). The effect of this setup is that dwarves practice siege engine operating and I do not lose endless stone (since dropping a z level preserves the stone).

This has worked perfectly in previous games, and in this game the stones are still not lost .. but they inexplicably drop an extra level through the solid floor (z-2). I first thought they were being destroyed, but noticed they all fall through 100% of the time.
Steps To ReproduceThe attached save has the catapults on continual firing mode, so have to wait just a bit for a dwarf to get to one and fire a rock. Then you will see it (stepping through in slow motion if you want), travel down to z-1 and then z-2.

There's a similar issue with all kinds of flying stuff: arrows fall through floors sometimes, as do body parts. I'm not compatible with Mantis' search feature, though, so I've failed to locate that bug report.

I got that problem with Ballista Arrows, the hit a Bridge and should fall one Z-level where they should get picked up but instead they fall 2 z-levels despite there is on solid ground on the first z-level below the shot
