Questions about performance

@snagglefox Great to hear!

I can't ping after my ACU was killed. Is this a bug or new feature?
Sadly this is neither a bug nor a feature. Pinging after dying is disabled because of a potential exploit. For more information, read this PR: https://github.com/FAForever/fa/issues/2259

Cybran hive drones are completely MIA. I only see the beams.
🤔 , the drones being missing is a bug - not sure what causes it yet. I'll make sure to investigate it before the patch hits in September.

edit: about the drones missing, could you describe what you did right before it happened? I have a hard time re-producing it.

Ah ok. Thanks for the info!

I probably should have mentioned those were allied hives. I was already dead. So maybe being dead or them being an ally's has something to do with it?

This is not a good reason to take away everyone's ability to ping after death.

1 - nobody is forced to allow observers in a match

2 - observers can cheat anyway if they're on voice chat with a player

If people want to cheat they can cheat. Observers using a console command to place markers in the game in real-time would leave evidence of cheating in everyone's replay file. Doing it through voice chat would be basically undetectable.

Nobody is going to cheat in a way that leaves evidence so blatantly. And if they did, we would catch them.

This is NOT A PROBLEM but taking away the ability of dead players to participate in the game is a BIG PROBLEM.

I can't even queue for ladder or TMM while a game is going on, and now you're telling me I can't even ping my teammates while I wait for the match to end? That's nonsense. Total nonsense. "Fixing" something that was never a problem in the first place. UN-FIX this!

Yeah, either this is described poorly and it's not just observers that can do it but anyone who died, or it's really not a problem at all, because observers always could cheat in many ways (like VC) and they really never did that by using pings.

The decision to disable the markers was made by two council members (if I recall correct) last year December, see also the PR where the change was made from that time:

If you do not agree with this change, please make a new topic. It is unrelated to this topic about performance (and stability).

If people want to cheat they can cheat. Observers using a console command to place markers in the game in real-time would leave evidence of cheating in everyone's replay file. Doing it through voice chat would be basically undetectable.
This is not the consequence of the exploit. I'm leaving it vague on purpose because I do not want to give it more attention than it has to have.

Played a fafdevelop game where ACU upgrade after it should finish got stuck and acu was constantly -7 mass.

(I was assisting ACU with cybran t1 assault bot)

This error popped up in the log:

Hi Crotalus, can you share the entire log and the replay ID?

edit: the error you provided is from a Mantis.

And timestamp as to when it roughly happened? And to what player?

Ah, I think I understand what happened here. Thank you for sharing.

edit: found and understood the issue.

I'm still not sure if this applies to games with observers off (i.e. most of the games) at all.

Edit: woops, meant to post this in the other thread, sorry

@Jip In the same game that Crota reported, MaximusXXX said at 38:21 that he was able to build t2 navy despite the HQ being dead.

oh no 🙂

I'll look into that too - thank you for mentioning it.

@crotalus It is fixed - thank you for reporting it! This was also the issue @excelsior (discord) described and @Crotalus experienced during that replay.

@zwierzak The replay desyncs for me and that happens to be MaximusXXX . Can you describe what happened?

@utopian Thanks to KionX we may have found out what caused this crash. It will not be part of the next patch because its deadline is too close - but we'll certainly look at it. Again, thank you for reporting it.

Is the fix live on the dev branch right now? Just wondering if I should warn people or not when hosting games.

The fix with the mantis is live - yes

I failed to reproduce MaximusXXX's error and the game now desyncs for me, too. Probably because of the Mantis fix.
However, while testing just now, I found new problems:

Game: #15195914
Timestamp: 20:00
Issue: UEF T1 Attack Bomber seems to do very little damage

Game: #15195914
Timestamp: 28:00
Issue: Cybran T2 Naval Support Factory auto-repairs VERY quickly

Log isn't much help, as I didn't have debug enabled. 😞

This is a known issue, it has to do with a change unrelated to performance. The Janus is hit hard too by that same change. Keyser is going to look at it this weekend.
