Just something small I just noticed. Sometimes characters aren't positioned on the correct place. For example I place Hoagie in the lab next to the carton near the match machine. Then I switch to Bernard who is in the lobby, I go down to the lab and Hoagie is suddenly on the left, in front of the time machine. Bit annoying but no show stopper. Playing with the 1.0.3 update under Linux Mint 19 x64.

They are not incorrectly positioned, they just move out of the way. Sometimes you can even see them moving aside, when another character steps in to do a task. For example when you try to fool Ed with Hoagie or Laverne, Bernard enters the room and the others leave.

As for the basement, I agree. It is a bit annoying that he moves so much. But it's not a bug or glitch.

Ok for me.

I found that in the past, in front of the car I couldn't interact with Laverne using Hoagie, it keeps pointing to the Mansion.
