Using movement-related skills bug

there is problem with skills like chain strike. example. when you have a person sitting or making private store and you will use this skill successfully, that person will be bugged. it seems like chained character is standing but you cannot move! it is because your character is still sitting/making vendor and to break this bug you need to press /sit or /vendor or /buy command.

in my opinion when dragged character is sitting it shouldn't be standing up. same happens with othell and tyrr skills which knocks target down or moving it.
