It is possible to remove levels and equipment by going through the process menu to Asset information > Edit structure

Make sure the correct level/asset to remove, is selected in the technical tree.

 

The main page of technical tree management has functions for removing the level. Actions always affect the asset selected in the technical tree

There are two types of deletions:

  1. Mark the selected asset as hidden and it will be removed from the property menu and will no longer be processed in any process in the program, but the level can be restored again if necessary. This is the recommended way to delete.
  2. Delete the selected level removes the level and cannot be restored to the user interface. The function should be used prudently.
