The Marathon (5 daily challenge win streak) help

[Romulus]

HI, I'm struggling to unlock this achievement. The Wiki says that I need to a) win the daily challenge whilst having at least a 0 win streak. The way I do the daily challenges is that I turn off mods and since I play with mods, my streak is always at least 0. I have won at least 5 daily challenges in a row and I'm still not getting this.

Do I have to win the 5 daily challenges without mods, and also does it matter if I die on runs with mods on (considering that there is a separate win streak with mods on)?

Marathon can't be unlocked on Repentance for now, it's a known bug.
Workaround: uninstall Rep, unlock it on AB+ to get its Steam achievement (either doing it again or using a debug command), then reinstall Rep and press alt+F2 in the stats menu to get its secret in Repentance.
