Do you also know a way to reverse that?
Because I did that about a year ago, and now everything is cluttered with bugged replays that I need to delete manually.
I also had the experience that yes, the error message is always displayed and even after minor patches, the game played out very differently. I remember watching a replay after a patch that did not address any of units that were used if I recall correctly. Yet in the replay, I saw the enemy MG42 mow down my full health Conscripts in a couple of seconds and other crazy shit.
What do you mean reverse it? Like just removing the launch option?
EDIT: I just realized aerafield replied with the same response......
