Just an FYI,

These mods are responsible for breaking the Huron and the Armed Wildcat.

Removing the AGM Aircraft pbo brings back the wild cats

Hi Iceman,

it is the AGM mod that is breaking the helos. In particular the two pbo's mentioned above.
Will contact AGM.

Further update, it is not a BI problem from what I have found.
The AGM Realistics names pbo is responsible for breaking the Huron, will find the mod responsible for breaking the Wildcat in further testing.
Thanks a lot for your help and sorry for any time wasted.

An update for you.
The Huron and Wildcat work fine on Altis and Stratis with no mods selected, when I try to place them on a 3rd party map such as Imrali, Sahrani, Isla Duala it then breaks with the symptoms described in the OP.

In the editor when when you are selecting the Huron or Wildcat the little icon to the right of the Helo name (believe it is the DLC icon) is not present when 3rd party maps are running, including on Altis and Stratis. The only time they work is in a pure vanilla setup.

Hi,

I verified the data after the patch had completed and no errors were found.
In my group, 2 others have so far tested this with the same results, the game crashes back to editor with the error message that I posted above.

Crash logs added, no Mdmp file.

There is no crash logs but after logging in to the game on the server we get a black screen where the mission select page should be and then when I check the server I get the error: Include file a3\functions_f\Params\paramGuerFriendly.hpp not found

I have done a quick google search on this error and it seems switching to Dev Branch solves this issue, however, we want to remain on the stable branch.
