Okay, so here's the skinny:
The new Arma 3 update is broken for everyone who plays on servers with mods. We need to downgrade to the previous version.
Open up your steam library and click on Arma 3 in your games list. Go to Properties - > betas - > enter "Arma3Legacy124" into the box and downpatch. It's roughly 850 mb to downgrade, but it's nessecary in order to play on our servers.
Be advised that this interferes with the regular servers that aren't using mods, since they're running the newest version, which in terms means that you can't play on regular servers until the problem is fixed.
When we know more about the problem and the solution for it, we will keep you updated. Stay frosty for now gentlemen.
Short Update from S1 & S3 since it's not perfectly clear from the above post: This weekend's Recruit Training and Unit Wide training is cancelled, so is the official operation. We will keep you updated.
