There is also a mod in the vault called 'Selection Fix', which fixed the UI Party selection problem. Even though that doesn't appear to be the intended use, based on the vault description. It made UI Party usable for me.

Did you save any of those replays onto your own computer? If so, you can search for that replay using the "Replay ID" field (embedded in the filename). You'll see their new name shown there.
If the replay is from over a year ago, make sure you update the default date range as needed.

Even when all players agree to a Draw, there is still a rating change for TMM? I've experienced the same thing, and was surprised.
How can you determine a winner/loser if it was a Draw?

But then I checked the games a day later, and they correctly say 'DRAW' and no rating change.
So it all worked out in the end, but that is a bit a confusing!

Fichom - Have you rechecked the game results a day or two later? They may correctly appear as a Draw.

Nvm, I found it!

Hopefully, this is up to date.
Not sure I can do a table join in the client. I need to figure out how to run an arbitrary query so I can play around with it.

For the OP's problem, searching for high-rated players is about the best you can really do.
There probably are not many 4v4 games where everyone is 2000+. There just aren't many players at that level.

Is the replay database schema published somewhere? The search function is pretty limited, but I can write my own SQL search filter. I have no idea what the available fields are. I'd need the table layouts.

It does look bad. Your ACU's regular gun stays on the enemy ACU, so it's definitely the targeted unit. The Mazer seems to have trouble keeping up with the changing angle. The way your opponents ACU circles around you at close range, makes me wonder if he is aware of this behavior and using it to defend himself.

Each weapon has it's own priority table, but 'COMMAND' appears at the top of the Mazer.

Also, exactly how did you set ACU priority? There's Snipe Mode, built into the game, and then there's mods that do it. Could be a bug in a mod.

You can also enable Group Stealing in the options. If you assign a tank to a new group, it is removed from the previous group.

Ah! I didn't realize that. Thanks for the response!
In the same replay, the Notha's attacked ground units, completely on their own, without any orders, so I was expecting the same here. They weren't on a Patrol order at that time, so obviously Patrol works differently. They act as Fighters-only when on Patrol.

This was in a FAF game played offline, but I have the replay available.
I had 2-3 T2 Fighter Bombers (Notha's) on patrol. They repeatedly flew over an enemy T3 MEX and didn't attack it.

This happens around 38:00 in the replay, bottom left corner of the map.
Replay attached. There was a DilliDalli AI in the game, if that matters.

For anyone seeing in this in the future -

PLAY a custom game FIRST. It can just be a 1v1 versus an AI. The client does not create all necessary files and directories until you play your first game.

Replays should then work.

Didn't anyone help you with this? I don't really know how to interpret your logfile.
Try launching the game directly, instead of through the FAF client. Does that work?

If so, create a new profile and make that active. Sometimes, there can be things written in the profile in the game.prefs file that can prevent the program from starting.
