C:\Users\*myuser*\Documents\Blockland\BlocklandLauncher.exe -dedicated -pathprofile c:\path\to\server folder
Ok I understand now. The command "-pathprofile" that you're adding to the end of the shortcut is telling it that it's getting its Add-ons and preferences from somewhere other than your \Documents\Blockland folder. If you just want to use the Addons and preferences in your regular Blockland folder, just make the target line say:
C:\Users\*myuser*\Documents\Blockland\BlocklandLauncher.exe -dedicated
Make sure to replace "*myuser*" with the actual name.
If you do want to use another folder for your server addons and preferences, then create that folder somewhere else and note the path. For example, if you create the folder ServerStuff in your normal Blockland folder, the path would be C:\Users\*myuser*\Documents\Blockland\ServerStuff. With that in mind, the target field of the shortcut should look like this:
C:\Users\*myuser*\Documents\Blockland\BlocklandLauncher.exe -dedicated -pathProfile C:\Users\*myuser*\Documents\Blockland\ServerStuff
