This is fixed in FAF Develop, and therefore fixed once the hotfix it out - thanks for reporting it

A work of art is never finished, merely abandoned


Had another crash today, offline Setons 3v3 with 4 Sorian Adaptives and 1 Sorian cheating. A few hours into the game so many units in play including a Paragon.

Sorry no debug, I got the classic GPG crash notification. Also not started through the client so can't confirm its on Devel but I did start a dummy multiplayer game using the devel branch via the client, then used a direct shortcut.



The log you shared is 42 seconds in - I'm afraid I can't determine the cause with the information you provided. I also can not find the replay in the vault - as that makes sense since you didn't start from the client.

Note that the classic GPG crash notification can point you to the dump file - but I suppose you closed it by now.

Not sure if I should start a new topic or post here, but for the sake of the topic here goes:

I was exiting the game. Have had other crashes earlier, but installed the new patch for the FAF client and verified the game files on steam, still not sure its related:
Earlier crash, log file only as the computer rebooted instantaneously.



warning: SND: Error playing cue 5 on bank 1 [explosions] XACT: Invalid arg
Looks like you Soundcard has trouble with XACT
Try to set your soundcard to Stereo only and disable all sound enhancements.
Read here for more information:


Ah, thanks!
Will try that as soon as I'm off work!
Much appreciated!


@uveso Configured my output as the topic described. (2channels=stereo i assumed)
Still crashed ~20min into a game. (Tried a Replay first, worked mostly fine, with a crash upon exiting)
Any of these point towards something?

hello HolyCrap,

i can still find those errors in your log:

warning: SND: Error playing cue 1 on bank 5 [music] XACT: Invalid arg

Please test if the game crashes if you switch off the sound:

Please make a desktop-shortcut from the file:


Open the shortcut (rightklick->properties) and edit the commandline.
Add "/nosound" at the end. Should looke like this:

    C:\ProgramData\FAForever\bin\ForgedAlliance.exe /nosound

Then start SupCom with the desctop shortcut and make some games.

FA crashed, but wasn't able to get the info from the pop up without force closing FA. Game crashed two games in a row, while I was building the Czar. I was playing in a 4 player survive map, black sun defense. Once I forced quit out of the game and error window, they were able to continue playing, but I was out of the game. I got the error:

"EXCEPTION_ACCESS_VIOLATION (0xc0000005) at address 0x0050dfd8
attempted to read memory at 0x0000005c"

The unknown symbol portion that followed stated, 0x00423221.

Included Log files below for the two games, in order.



I appreciate any help!
