That cutscene is now working.
The screen goes black for a second (otherwise you would see a bit of a glitch that can't be avoided with a camera as it seems to override camera's) and then there's a meshswap for Lara which places the crossbow in her hands and then another meshswap when she places it, and at that same time the crossbow also appears on the pedestal.
But yeah, smart use of camera angles can help a lot to hide stuff.
