First of all i’d like to say that the new map is gorgeous. I really liked playing through it. The new boss is sweet too.
During my exploration of the nooks & crannies of the castle i noticed a visual bug where you can look past the walls into the void.
First it was the main hall thing at the beginning (forgive me but i don’t know the location names on this map yet) to the right in the corner:
The second time i noticed the same error it was somewhere after falling down, i can’t really say where exactly since i got severely lost after 2 minutes:
