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.

Try reporting bugs on their website. Pretty sure they would rather monitor that

With that said, AN EPIC mod as such - used it for years already - just recently experienced this, same with a few others in my group. Some experience it, others not - cant wrap my head around it.

Again, another file blocked by Battleye:
13.08.2017 16:31:33 - Blocked loading of file 'D:\Spill\Steam\SteamApps\workshop\content\107410\463939057\ace_advanced_ballistics_x64.dll'

I've also contacted battleye support about this.

But, its weird - these files are not blocked consistently - feels almost random, but it gets in the way of having fun - as we're removed from the game.
