I'll fix it if I can replicate it, but struggling to replicate it.
start_at = my_location locations {
my_location : location "You are in a room." ;
my_location_2 : location "You are in a room." ;
} objects {
large_branch_1 : object "a large branch" at = "my_location" msg="LARGE";
large_branch_2 : object "a large branch b" msg="LARGE 2" at = "my_location_2";
small_branch_2 : object "a small branch" at = "my_location" msg="SMALL";
}
