opened the game, checked the content, found my add-on's weren't active, as well as others that were previously active. playing on V1.2.1 S5 GOLD-Public, with launch options at -compat.

here's a screen shot:

hope you can help me. thanks!

Giving this a bump, got the same problem on my Mac.

As I posted in a different thread, I assume herein the problem lie:

My Windows PC:

My Mac:

Namely all the addons are not showing up as "Mac Compatible" in Steam.  And no, the "uninstall and reinstall" option does not fix it.

Same here; playing 1.2.4 S5 Gold Public. Redeeming/Linking/synching uneffective.

I have the same problem as well on my Mac. Uninstalling the game and reinstalling it from Steam did not help.

I'm confident that a solution will be available soon for us, we just have to be a bit patient :)

We can still play with the Vaulters in the meantime !

The problem appeared to have been fixed. All of the updates are now available and working in game.

yup, fixed in mine as well.
