What other mods do you have installed? I cannot reproduce this in vanilla or Calamity.

other than a bunch of weapon and boss packs, the only major mod is fargos

Eternity mode in Fargo's will softlock you during the day, but I never fixed it since it would be a pain to do, and it's virtually impossible to win normally anyway. The softlock at should not occur at night.

If you want to fight her during the day, I would suggest briefly disabling eternity mode; If you find that her weapons are too strong, you can nerf them in the mod config.

I was afraid i was Eternity
I did disable it, but even after reseting the game several times, the Eternity pallate swaps have not changed, and I feel it's busted
I'll just have to remember next time, Fight her before activating Eternity

I just tested it, when disabling eternity mode, the boss sprite remains the same as the eternity version, but the attacks return to normal and there is no softlock.

Is your issue resolved or is there still a problem?

it's still soft locked, it still does what I initially reported

It must be a different mod then. You'll need to disable mods until you figure out which one is causing the issue.

I did, i turned off everything but this mod and it was still unkillable
only a full new playthrough worked unfortunately

I am using the steam release of the mod, with Fargo's enabled *or* disabled, and I cannot reproduce this issue either way.

If you can give me explicit steps to reproduce the problem, I can look into it, otherwise, I can't do anything.

it's fine, I don't know if there is anything else that can be done
thank you for your help
