I playing the main story. No cheats, no mods. Until some point, the achievements worked, and then suddenly stopped (there are no warnings about disabling achievements on loading). On another save with a different character, the achievements work.Hey, the achievements are disabled on the sandbox mode and they will not trigger on the campaign as well if there are any mods installed or cheats are enabled. Please let me know if the issue is persistent on a campaign with no mods installed and cheats disabled.
