The 3 -in -1 bucket always uses the piping function in which the hollow is raised.
When unloading in buildings or under the roofs, it triggers a unsightly collision.
If you change the command in the F1 menu,
This will be reset again at the latest after the next unloading.
Therefore, the bucket has been adjusted to avoid this,
The push floor (without advanced function) is now always used to unload first and also by Autodrive
Have fun with
