Potentially Bugged Room Transition(Dawn of Souls)(DSVania Rando - 1.4.5)

[Stingerman06]

So I typically do relative chaotic randomizers(still reasonable) after beating a game, and I decided to tackle DoS, though I gave this specific seed a very thorough attempt and found one room transition that effectively softlocks the game completely. I don't know if there's a bug related to progressive flags that can cause this, but I'm attaching the seed no-spoilers file that generated with it. I tried succubus glitching to get access to certain rooms in hopes that I can beat the seed, but I'm still new to using it. I can get very far without Rahab's soul, but one room that requires me to go down for the room transition is impossible, and the 4x4 underwater room the regular way(from the top right) without the soul is next to impossible as far as I figured.

Further seeds I made, I was easily able to traverse rooms and haven't softlocked as far as I know, but I've been savestating 10x more than I normally would have since this issue. For reference, any unexplored rooms are Rahab soul required rooms and the pointed location is the transition that causes the crash. I don't know if the Celia encounter would have anything to do with this, but that was one of the first rooms I cleared that sets event flags(as far as I know).

Edit: Forgot and don't know how to mark this as a Bug
