A character will keep the he is using props until the code picks up a @remove propsName from Character.
For example, if you are previewing line 2777 in which @Character1 had a book then you decide to go quickly preview line 10 before the end of the scene of line 2777, @Character1 will have the book in hand because the code @remove book from Character1 didn’t take action yet. To fix that bug go back to line 2777 finish the scene. it should be good to go.
