First of all I love this game its amazing haven't had such great time hunting bad ends in such a long time and was constantly impressed by the changes based on how you handled the area. One bug I encountered however is that I get stopped by the Cerberus statue in the boss rush not triggering a fight and also blocking the path forward. Not a big deal I had already done pretty much everything else. I was on ver 1.4 although I had done some of the early game like the sea market and tower on ver 1.3. I defeated Cerberus normally and then again once during the boss challenge and this was my second time entering the boss rush area however I didn't get to Cerberus the first time, I had left the area after one boss to go fill up on consumables.
