Catapult,balista,trebuchet and siege tower problem

[Morningwarrior]

there is a bug happening with the siege machines that can be fixed or mounted, after you put them in the map editor in any mode and then activate the created map for testing, the siege machine keeps repeatedly mounting and dismounting, getting stuck or unfixes, this does not only occur with the ram, tortoise machine,siege mantlet and hwacha but the rest of the machines such as ballista, catapult,siege tower and trebuchet have this problem.
