I just downloaded the Apocalypse 1.6 mod from the first page and the power icons are still missing when using an XBox controller. I've read through each post and saw Cry Havoc was able to fix it, but the links to the updated powerstyle file are dead. I checked in the file included with the 1.6 version and they all say "apocalypse_icons1.png" already, so I'm not sure what to do.
Of course it's not game-breaking and the mod itself is great. Thank you Cates for making it!
