i mean, what i could do is clone the chest to another surface, revive it, apply the math, copy it back and then destroy the clone, nut it would be more convenient it the api just works
and as for why vanilla works, its just that the functionality isn't exposed to the lua api mods get to use yet
fixed in 2.0.5 (i'm still waiting on the above forum link to make the code cleaner again, using the other method that got ghost support in .29 for now)
the reason i asked for a new screenshot is to verify the mod version numbers, and this same link ofc points to the same image, and in either case you need version .29 or above and currently only .28 is stable
