Again i'd say less a Bug and a more mistake after the rework to the first part.
But OBE is unlikly to fix it if you don't point it out to him.
Because he would (and I don't blame him) rather concentrate on continueing the story.
Before sparing the time to go back and look for errors and mistake's.
He wouldn't even be aware he had made in the first place.
Trust me if you let him know he well sort it out as soon as he has the time he won't ignore it once he's made aware.
He's like a lot of Dev's is new to game making and limeted on the time he has to create it.
Unlike some though and I can think of a few that do.
He wont just ignore issues even once told about them.
And just continue to make more mistakes instead.
Because OBD takes pride in his work. (and he has every right too in my book)
Thats why most that play his game are more than willing to wait for his releases.
And won't hound him for the next one because we enjoy his work so much.
No matter how much they really really want too
