One other person has reported this issue since the last update of both RHS and 3CB factions. They resolved the problem by redownloading the mods as one of them had become corrupt (never did find out if it was RHS AFRF or 3CB Factions). We use both mods in our Ops on our bikey'd server and have not seen this issue. Maybe a mod version mismatch? Are you using the latest version of RHS, 3CB and CBA_A3?
If you could try and reproduce the problem by quickly building a mission using just RHS, cba_a3, and the 3CB Faction pack, please pass it across and I'll investigate further. Where are you seeing the problem? Does it appear on screen on mission load or is it just appearing in the logs? The more information the better. If any one else is experiencing the same problem and can provide any steps to reproduce the issue, it would be a great help. I would suggest verifying / redownloading the mods first though in case they are corrupt as that is currently the only fix I know of.
