Hello!
I did it few times with friends on legend difficulty, message popped out on chat, we even measured that taking out little rat after big guy took us no more than 13 seconds. We still didn’t get it in Okris book, try to do something about it as this bug is happening every now and then since 2019 as I was searching through this forum and reddit. To anyone with similar situation - does doing it on cata works fine? I didn’t try yet.
