Descriptive Problem Summary:
It seems both overlays and underlays adopt the icon of the atom they're tied to when their own icon is null. If you add an overlay with a null icon and pixel_x=32 to a blue circle, two blue circles will appear. This effects both atoms and images being used as overlays.
Numbered Steps to Reproduce Problem:
- Create something with its icon variable set to null.
- Add it as an overlay or underlay to something else.
Code Snippet to Reproduce Problem:
An invisible overlay or underlay should be added.
The overlay or underlay adopts the icon of the atom it's being attached to.
Does the problem occur:
In other games?
In other user accounts?
On other computers?
Yes, Metamorphman independently discovered the bug as well.
Did the problem NOT occur in any earlier versions?
This seems to be a really old bug. It happens in v470 which is about how far back I can test without completely reinstalling BYOND.
Use blank icons in place of null icons.
