How to remove:
1. Go to your Add-Ons folder.
2. Search for "datablock PlayerData" (as a part of file, no quotes) in add-ons folder somehow.
3. Open all results in Notepad, press Ctrl F and again, search for "datablock PlayerData" minus quotes.
4. Within the datablock, look for a line that reads uiName = "Something";
5. If it doesn't exist, put the following line within the datablock:
//within the playerdata datablock
uiName = "";
6. Save the file.
7. Repeat 3 - 6 for all files that were found.
8. Done. Open Blockland, make a server, and when you make a minigame, there won't be a crapload of "Standard Player" entries.
Also, see this thread:
