this is not a big deal to solve first of all make sure you started up your arma once so it made player profiles if you done that check you mods/download path[ C:\Program Files (x86)\Steam\steamapps\workshop\content\107410] and arma 3 path like this [ C:\Program Files (x86)\Steam\steamapps\common\Arma 3 ] if you place the paths like this your steam will update your a3 mod and you wont have double mods. wenn you done the path save it in right bottum and restart steam and a3 launcher.
sorry for not responding sooner but ocp is open chernarus project which ds houses replaces in chernarus redux and now the launcher and everything works fine with my server no problems anymore so it might be OCP and i had no errors when server checking my server during the period that i had the problems @maca134 @SCHMURDA
The bad point I wish to bring up is The Arma 3 launcher has changed from you where given a choice on the update eg220.127.116.11 to 1.0.4.. But not anymore, the Arma 3 launcher here forces the major updates now. So in effect we do not have a choice which is not good, can this be reverted back so gamers have a choice?.
