Soft lock on Core map with new Mirage mechanics

Got myself soft-locked on "Mirage of Core". Went inside one of the small arenas, but the boss was outside of the Mirage. Now I can't go out as portals are disabled.



Edit: I feel stupid right now. I forgot that there is a F7 exactly for this purpose.
If a mod can see this, can hide/delete post. Thank you.
