I updated Arma 3 to 1.54, deleted all of the outdated 506 mods (@506th, @CBA, @RHS, and @ace) and downloaded the new versions and installed them but now every I log on to the assault server, I get an ace version mismatch and also missing addon error: pja305. Any help would be appreciated since we have an op this weekend I would very much like to be ready. Thanks to all.
