FA2 won't load override art from ecache for SNOW theater only?

[ATHSE]

Example image of the art properly substituting in URBAN & TEMPERATE but not on SNOW maps: https://www.ppmforums.com/files/theaterglitch_751.jpg

All the building art is in the same mix, so permissions or corruption is not the issue, nor is it related to any particular filename. Likewise putting the art into an expand.mix instead of ecache.mix changes nothing.

This only occurs for override buildings that use the same names as in the original ra2.mix, it doesn't happen if the art is renamed via Image=xxxx for the modified building. In the cases where the building had no snowy art, and otherwise requires no change, it saves space to just include the overriding snow art, and thus the name has to be kept original.

It would seem to be a loading priority issue, one where theater rules are applied after the original defined name is loaded.
