Run-Time Problem
Tried to make the player part of something (P63)
    

Most problems are detected when Inform translates the source text, but this is one of the exceptions, a "run-time problem" which emerges only during play.


The player is not allowed to be joined to other physical objects by being part of them, so it's not legal to try something like now the player is part of the Oak Tree or now the player is the branch (if the branch is indeed a person which is part of the Oak Tree).
