In very specific conditions, (It depends on the distance of the container) it can happen that the lift brings the parts not to the visual connected but to the container in front of it. This bug can be reproduced. Place two ind. container towers on foundations in a row, the connections of the containers are showing to each other. The distance is exactly the distance you need to connect both towers with one conveyer lift. Now when you connect two containers in tower one, let’s say the 2nd to the 3rd it may happen that despite of the correct look the parts are delivered to the 3rd container of the neighbor tower. Despite of the visual appearance the lift is virtually connected to the container in opposite position.
Don’t know if I could explain myself, please ask and I try to detail.
