Descriptive Problem Summary:
There are two types over overlays - those that inherit dir from their parent, and those that don't. Usually, they can be distinguished by the fact that when the dir isn inherited, dir is 0. However, those two snippets produce overlays that are *completely identical* when looking at their vars, but one of them inherits dir, and the other one doesnt

icon = 'some_icon.dmi'
// This overlay inherits dir
overlays += "some_icon_state"
// this overlay doesn't inherit dir
overlays += image('some_icon.dmi', "some_icon_state", dir=2)

// both overlays have identical vars

When does the problem NOT occur?

Did the problem NOT occur in any earlier versions? If so, what was the last version that worked? (Visit to download old versions for testing.)

Avoid using the += "some_icon_state" syntax when adding overlays

Not actually a bug; I've moved this to Feature Requests.

The difference between inheriting dir or not is an internal flag that gets set when you set the icon_state for an appearance.
