I couldn't open he control command when I was out of the mansion then I saw that I had this error. i'm sorry if this appeared before and I didn't see it but does anyone know how to fix this?
You've posted this under the wrong mod, Aric's mod does not have bountysell. Ralph's version of Aric's mod has bountysell. https://itch.io/t/1036577/ralphs-modded-arics-mod-097-standalone-hybrid-expansio...
Also, double check that you have the latest version and that you didn't mix up the files between the 2 mods.
