[Rep+] Found an infinite loop between dark room and the void

[Ties]

I was playing with Tainted ??? and after beating mother I went to the void in hopes of finding an r key. I got red key from defeating a boss and found a red sacrifice room, which I used to get to dark room. Since the delirium portal spawns with a 100% chance after final bosses in Repentance+ I got the portal again and this brought me to a brand new void floor with the exact same layout, basically creating an infinite loop until I found r key as the dark room was an entirely different floor each loop.

Don't know if this was alr known but I thought I'd share cause it was a pretty cool gamebreak
