Дело не в имени пользователи, а в имени папки по адресу C:\users\кирилица... вот тут должно кирилицы не быть - это и исправлял и всё запустилось. Хотя год назад я играл на этой же винде под этим же именем пользователя и всё работало.

я делал по этой инструкции:

несколько реестровых строк поправить не удалось, но вроде всё работает)

Hello @Odd-keys

Somehow I have 2 accounts....and...I was using the wrong one. My bad. I'm good to go now.

I am getting this error as well. No joy with the above fix @magge
I am on windows 10, have norton but disabled everything to attempt it. Have deleted game.pref, all my mods, the game itself, the launcher, restarted comp, moved it to different drives, and even did one final try with admin

Share the log - that way we can tell you what happened.

Also have this issue. Uninstall and re-install doesn't fix it

update: make sure to un-click "remember me" - that fixed it

Got the same error. Found no way to fix it right now.....

Cool thank you for information

The separate rectangle you are talking about was from one of those deprecated mods in the last big patch.

I have determined the exact option that's causing the error. It's... "Use Alternative Start Sequence"? I am in awe something so innocent-looking could be the problem.

Edit: I played around with the function "AlternativeStartSequence()" in the mods's gamemain.lua. Emptying the function does not fix the problem. Replacing it with the contents of the else statement—the line 84 in particular—did, however. The rest is beyond me, unfortunately. I do not understand why recursively calling OnFirstUpdate(), which seems to call UIP.OnFirstUpdate() every time, results in the replay working properly. I checked that function, and it's completely empty.

Edit 2: And it has to keep calling itself in particular. Making UIP.OnFirstUpdate() call itself in its own function in UI-Party.lua does not fix the problem.

Edit 3: The only fix I can imagine is a workaround, and it's to add a check for if the session is a replay and not trigger the alt start if that's the case. This made me think; if you could also switch between players during a regular match, would this problem appear also? I launched a quick game alone, and no, this does not seem to be the case. The rarely repeating errors that seem to be the prelude to the lag once you flip from player to observer seem to be absent, also.

@ladderff i use it with win10

@magge @Nvrnight this issue has already been fixed. It probably was the button on the "Play Now" page

I was never a big fan of third party software, the game is still using only 2 cores even with a software like that...~

I think the best way to get more performance is to keep ur system clean and get the performance mode on windows, also check if u can overclock and look for them ram, is it running in xmp mode? If not u will let a good piece of performance on the table.
