Mutant island bug repeat again with Sinister epic chapter 1?

LordPSN

I remember same thing happened when Mutant island was released.
Players thought that it is a bug and re-did their path and remember what happened next? 😬😬
Now look at the Sinister chapter 1 epic difficulty (for me).
Well not going to name anyone for obvious reasons but a certain YouTuber has said now that we can do it.
Guys.
This is same as Mutant island bug!
Do not do it till @Kabam Miike or some other mods confirm it!
