We're pushing a large content pack update today to prep for the incoming whitelist. If you want to, you can shorten the time this update will take by following these steps if you do not already have BTsync running:

Rename @A3GCP to @AKBCP

Rename @A3GMP2 to @AKBMP

Launch BTsync

If BTsync has already started syncing before you could do this, don't worry; just let it continue and everything will be fine when it finishes. Just make sure you have overwrite any changed files enabled in the file prefrences.
e.g.: https://i.imgur.com/ED1BtHb.png

We've also added the new RHS faction @RHSGREF in addition to updating @RHSUSAF, @RHSAFRF, and @CUP_Terrains. If you have downloaded these separately from another source like armaholic or the steam workshop, just make sure they are the most up-to-date version and they should work.

After you're done updating, you should have all the files found here:

Make sure you change the file names in the launchline, launcher, or however you run the modpack.

Thank you for your patience.
