DarkRP - Some players can't see jobs

[Pazda]

Hi, I'm having a serious issue with DarkRP at the moment.

Some, but not all, new joiners are not seeing any jobs listed int he F4 menu while everyone else is. This is around 3/15 people on right now that have the problem.

They say they get hte following console error:

[ERROR] gamemodes/darkrp/gamemode/modules/f4menu/cl_jobstab.lua:355: bad argument #1 to 'ipairs' (table expected, got nil)

I don't think there's any errors in my jobs file, and I never edited the erroneous file.

This seems to only occur with players who haven't joined before.

ANy ideas what's going on?

THianks guys!

Edit: I think it's just a derma issue, because people are able to use the commands to become those jobs just fine.

EDit 2: Here's some more errors people got:

[ERROR] gamemodes/darkrp/gamemode/modules/f4menu/cl_jobstab.lua:303: attempt to call field 'PerformLayout' (a nil value)
1. unknown - gamemodes/darkrp/gamemode/modules/f4menu/cl_jobstab.lua:303
[ERROR] gamemodes/darkrp/gamemode/modules/hud/cl_hud.lua:273: attempt to index global 'RPExtraTeams' (a nil value)
Warning: Unhandled usermessage '_Notify'

And someone just posted me their full error:
[ERROR] gamemodes/darkrp/gamemode/modules/hud/cl_hud.lua:273: attempt to index global 'RPExtraTeams' (a nil value)
1. drawPlayerInfo - gamemodes/darkrp/gamemode/modules/hud/cl_hud.lua:273
2. DrawEntityDisplay - gamemodes/darkrp/gamemode/modules/hud/cl_hud.lua:342
3. unknown - gamemodes/darkrp/gamemode/modules/hud/cl_hud.lua:401

I haven't edited any of these files.

Edit 3: I returned cl_hud.lua and cl_jobstab.lua to default, nothing is fixed.
