when i start the final boss fight dr foetus doen't spawn and I can't continue it prevents me do any% speedrun.The video: https://drive.google.com/file/d/1PahlWztdilYdANy0zZMEkf8eAzeE1McP/view?usp=share_link

Hard to say from that alone. Does it always happen? What version are you running? Are you running 60fps and 60hz? Can you show the footage when entering from map?

La seule fois ou j'avais eu ça , c'était sur une version crackée il y a de très longues années, jamais eu ça sur la version steam. Tu run sur quelle version ? La version steam normale ? La version steam "ogversion" ? N'hésite pas à nous donner plus de précisions.

Im ina cracked version on the game, I attempt to download another version and i attemp but don't work

This glitch has also happened to me when I was testing out the og version I have no idea why it happens.
