This is not a bug. In BYOND's big icon format, the regular icon state is the thumbnail of the fully sized state, and to get the individual 32x32 pieces you need to use icon_state="thing 0,0", icon_state="thing 1,0", etc. After calling Scale() you were sticking with the same icon state as before, which would have applied the 32x32 thumbnail icon to your atom.

A single atom cannot show an icon larger than 32x32 at this time. To show the full 64x64 size you need to use overlays with pixel offsets, or additional objects, and use the individual state names like "0,0". You can save some work by using Shadowdarke's BigAtom library.
