A new way to update the items is now available:
To force an update when your mod is installed/uninstalled do this:

• create a file called "base.config.patch" inside "/scripts/blshieldconfig"
  
• Inside "base.config.patch" put this code:
  [ [ { "op" : "test", "path" : "/blshieldaddons" }, { "op" : "add", "path" : "/blshieldaddons/-", "value" : ###### } ] ]
• Replace the ###### with a random number, if possible make it random.

After that, the shields will recognize that there is a new addon installed and will update.

Added "displayName" tag in "manufacturers.config" so that you can change the name without breaking the shields.
