Orientation of frozen entity

[sakuro]

I've recentrly released K2 Sentinel which brings Krastorio2's Sentinel (Small radar like building without chunk scanning function) to the base game.

To support Space Age, I added freezing to Sentinel. This means adding heating-energy and frozen_patch to its defnition and let reset_orientation_when_frozen = true. Now I need to add a snowy/frosty overlay image, so I checked in which orientation the sentinels freeze. I thought the 0-th frame (diagonal, the antenna on top-right) of the sprite of sentinel would be used but it is not true. Looking at the screenshot, 17th or 18th frame (antenna on top) may be used.

Are there any offset to its orientation when an entity is frozen?

It looks like in case of a radar, when it is frozen and that flag is set, the orientation is reset to a default value at which a radar starts, which is orientation=0.15.

Thanks!
