I've even tried uninstalling all mods excluding AAI Containers, Merging Chests, and this reskin mod but the graphics refuse to take effect. Am I doing something wrong? Is there some setting I don't know about?

same issue :\

Yep, sorry guys, was taking a long break from Factorio. Anyway, I've updated the mod to work with Merging Chests 5.0.0 and up.

P.S. Will try to update for Factorio 2.0 as soon as it comes out.

Okay, so the mod has been updated to Factorio 2.0, however, there are some kind of compatibility issues between Merging Chests + AAI Warehouses when combined with other mods. These issues are not related to this mod however, just be aware.

Thank you! It's all working now. Version 1.1.110.
