What version are you using? 1.5 or 1.6?

The mod is calling "Listing_Standard.Label()" with parameters that don't exist in your rimworld version, my guess would be that you're using 1.3 or 1.4 but that might not be the case?

I'm getting this too, on 1.5. Additionally, the debug menu also fails to load while the mod is installed. This is my error log after trying to open Mod Settings and Debug Menu. Mod list is (in load order): Harmony, Core, Royalty, Ideology, AutoArm

Thank you I will work on this today. The 1.5 push was a little rushed. I started making the mod in 1.6.

Small note, this bug only seems to be happening in 1.5. After the 1.6 update, it loads both the settings and debug menus

Appreciate the effort and support of this mod! I am another one seeing this issue in 1.5, waiting to move to 1.6 when a few more of my vital mods are updated which I assume is also the case for other people still on 1.5.

Fixed with the latest update Unsubscribe and resubscribe to push the update
