Floating dragon scales

[gregorp]

I'm on Vlad's Tower, Level 1, and killed a Gray Dragon on an "air" tile while levitating via a ring. I got a message about it's body falling away and disappearing, but it also dropped dragon scales that are just "floating" there in the air. Seems like a bug that the scales don't also fall away.

Thanks for all your work!

mksobj_at doesn't call flooreffects before placing the object onto the map (and most of its callers can't handle it failing to create an object, so adding a flooreffects call in there isn't exactly a simple solution either). This is what's used for creating dragon scales after a dragon dies. Other things have similar problems, e.g. stoning a monster over the chasm leaves a floating statue.

I'm not sure what the right solution is... could use something other than mksobj_at for these scenarios, but I suspect it'll be a lot of work tracking down all the places it's used directly and indirectly.

It's the same story with mkobj_at, too, though I don't know if there are any cases where that can be called over a chasm.

This has been fixed for a while now in bfd419f.
