Job Limit

If you are using Qbox, the maximum number of jobs is determined by your qbx:max_jobs_per_player convar. If you are not using Qbox, or if the convar is not set, it defaults to 3.

To change this, you can go to server/editable/_config.lua > Config.DefaultMaxJobs

Custom Job Limit

To set a custom job limit for specific players, add their framework identifier to the Config.CustomMaxJobs table, along with the maximum number of jobs they are allowed to hold simultaneously.
