I have the same bug some other people already reported in this thread:
On the NTR route, after eating at the duke's castle and reading the letter in MC's room you are supposed to go to sleep, but it's impossible to do so since the bed can't be interacted with. I already tried to interact with all the people in the castle and went to the other rooms as well as watching the newly unlocked scenes in the Recollection room, but none of that unlocked the option to sleep.

Futa Fantasy Could you please look into this and fix it? Doesn't seem to be a bug everyone encounters, but including me it has been several people so far. I can't proceed with the game because of this issue.
