late to the party like always.
I had the same problem as Sunette
But i figured if i put it on Homecoming.exe like how Serbwizard said to.
then after made a shortcut with -patchversion 20200628_1602 -auth 51.161.76.201 -patchdir homecoming
after the " " target. you log into the game.
but only works if you add the right patch. if they update anytime you have to go back to https://patch.savecoh.com/manifest.xml and get the right patch number
i used the line with Homecoming 64bit
