Persistent Mod Issues - RESOLVED

[GySgt (Ret) Sanderson]

I've been struggling with the same mod issue for about a week now. Heres the low-down:

Whenever I join an official 15th MEU (SOC) server I get booted off because of a "Missing Server Addons:" warning for these following mods: ffaa_data, ffaa_ar_supercat, ffaa_lcm. 
Here is a Screenshot of the Mods I am running as of 8/18/19. 
And here is the latest image of the error I am receiving. Please disregard the topmost error, that is a flight-ops specific issue. 

Heres what I know/assume:
 

I am able to make it to the role selection screen and green up, this indicates that it is not merely a bi-key/bisign issue. 

I am able to connect to unofficial 15th servers such as, but not limited to: SOI Backup 1 & 2, Flight ops 1 & 2, Archer 1 Primary, Archer 2 Primary, Archer 3 Primary, Public Server. I see no obvious mod missing/added, everything seems to load fine and works smoothly.
After role selection, I am faced with a red box titled ACE Addon Error, Missing Addons.
I assume the issue is a result of the Lythium mod somehow, many different people have advised me as such.

 

Here's what I have attempted:
1. Re-joining the server

2. Re-launching Arma

3. Closing steam and Arma and re-launching

4. Unloading all Mods and joining via the launcher's browser

5.  Restarting my Computer

6.. Removing the Lythium Mod

7.. Deleting all files in the Arma3/!Workshop/ folder and in the /AppData/ folders (roaming, local, and localLow) containing the keyphrase "ffaa" and trying steps 1-4 again.

8.. Verifying the integrity of Arma 3's files via Steam.

9.. Deleting all of my 15th steam collection workshop mods and re-installing them. 

Note: There is currently no file with ffaa in its name on my desktop. I searched "This PC" for the keyphrase "ffaa" and it came up blank - Save for a windows backup, and anti-virus file.

 

Here's what I have not tried:

1. Deleting all mods in both local and workshop sections, and re-installing only the 15th Mod Pack.

2. Step 1 + Arma 3 Uninstall & Reinstall

I thoroughly appreciate any and all help I can get on this issue. My steam account is: https://steamcommunity.com/id/55236272234 Please message me here or there if you have any time to help/have any ideas.

TL;DR: Persistent Mod issues, tried almost everything, No file/mod exists in my computer which the server has the issue with.

Others were having this issue as well. One of them solved it by unloading all mods on the launcher and then joining the server via the launcher which should force you to load just the required mods.

The "ffaa" could be in a pbo of a different name. If you do not have luck with this, you can find me and we can Teamviewer and look into the issue if you wish. 

[Cpl Bridger]

Maybe an outdated or corrupt copy of "15th MEU (SOC) Mod Pack" (https://steamcommunity.com/sharedfiles/filedetails/?id=1644588962 ) as the latest update removed the LCM (considering ffaa_lcm is one of the indicated errors).

 

Might be worth trying a repair on individual mods from the Mods tab of the launcher (right click -> repair)

[Sgt Kanefield]

The 15th mod pack update also removed the Supercat, so that is most likely the issue.

I just deleted and re-installed the 15th Mod Pack. Same issue. Seems to be something else, thanks for the try though.

Try to put the addon folder into the antivirus ignore and then try to repair/redownload those. I had a similiar problems in the past where steam cannot do anything about it.

 

Also check your quarantine.

This is Johansen. I am currently on Sanderson's system. 
Supercat was solved but ffaa_data still appears. 

Can't seem to find a mod that has that pbo. @Capt GraffHow would I go about finding it with different name?

I’ll almost certainly be able to fix this when I’m on (a couple hours), if it is not solved by then. @Cpl Sanderson

[GySgt (Ret) Sanderson]

Thanks, I seem to have solved it for the most part. In the 15th MEU (SOC) Mod Pack there were corrupted pbos, consisting of data, supercat, and lcm_data under slightly different names. Deleting them solved the issue and arose another. Now when I join the mod check server I am prompted with an issue with the MEU Factions PBO. Currenttly attempting to use a dropboxed version of the mod pack and joining off of that. Will update further.

[GySgt (Ret) Sanderson]

Dropbox version didn’t work. Don’t know what’s happening.

[GySgt (Ret) Sanderson]

Issues resolved, deleted ffaa_lcm_data, ffaa_ar_supercat, and ffaa_data .pbo's from the \Arma3\!Workshop\15thMEU(SOC) Mod Pack folder.
