Advanced Combat Environment 3 (ACE3)

ACE3 is the collaborative efforts of the former AGM and CSE teams, along with many of the developers from Arma 2's ACE2 project.

This mod is entirely open-source (we are hosted on GitHub[]), and everyone is free to propose changes or maintain their own, customized version as long as they make their changes open to the public in accordance with the GNU General Public License.

ACE3 is built modularly, thus a team can maintain its own tailored version, excluding a select number of components that they don't like, or which conflict with other addons. Larger components themselves, like the medical system and other core features also include various customization options, allowing mission designers and communities to tweak the overall experience.

I keep on getting a bug that whenever i have this mod offline i get a ballistic error for some reason
It is a Client/Server Addon Mismatch. I have already tried anything I could find, including uninstalling and reinstalling the mod (and the game) I have tried deleting every trace of the mod and reinstalling. I have even tried using an older version. My friends and I have the same mods and the same version of said mods. The exact error is: Client/Server Addon mismatch. Client has extra addons: "ACE_MEDICAL_MENU"
Any fix for the "ACE_MENU_MEDICAL" error when joining multiplayer games with Ace?
