HAIL type Projectile not impacting

[ErminioLucente]

It seems like some projects on rare occasions do not impact the ground and just get stuck, or fly along the floor without inertia set. The projectiles do respect gravity/fall acceleration even if in the video it appears to float.

its been confirmed that PROPERTIES = STRENGTH_BASED REBOUND_IMMUNE is the culprit.

This video demonstrates the issue.

This video demonstrates it in possession mode. It consistently does this if autoaim/PRIMARYTARGET is set, it does NOT do it if this is set to 0.

After a bit of investigation, I think this is because it sets TMvF_Unknown10 in thing_fire_shot here:

        if (((shotst->model_flags & ShMF_StrengthBased) != 0) && ((shotst->model_flags & ShMF_ReboundImmune) != 0) && (target->class_id != TCls_Door))
        {
          flag1 = true;

That makes it a duplicate of this issue: #2811
