Korg'ii hold

Is there any way to get into the hold after ula is gone, or using a save editor. I completely forgot about her and got distracted by salvicite hunting

Open the Console with F12 and type
flags['ULA_LEAVE_TIMER'] = x;
x is your current time passed in minutes (Days * 1440 + Hours * 60 + Minutes). Ula should appear in the cave you met her.
Or open your save with a JSON reader and search for that flag. Text Editors like Notepad work, but it's not very readable.
