tpg.ent.flag.server:Drop

Enter STATE_DROPPED at (roughly) the carrier's last position, tracing straight down to land it on solid ground rather than floating. A carrier killed in the air (in an aircraft, off a cliff, rocket-jumping) would otherwise leave the flag floating at head height with a 100u pickup radius nobody on the ground can reach -- it'd just sit there until the return timer. The trace runs through world + props/vehicles (but not players, and not the ex-carrier) and drops it onto whatever surface is beneath; falls back to the old head-height spot if nothing's hit (tr.Hit false, or the trace went out to the skybox).
