It's in the download version of the game:
While running game code:
File "game/starting_script.rpy", line 27, in <module>
AttributeError: 'Room' object has no attribute '_accessible'
is this when you're starting to load an old save? This bug seems very odd, didn't have it in my tests on a new game last week when I was doing the tests :o
I had this come up on a fresh install and on a fresh file since I had a similar issue when trying to use an old save
