Using the command ".make gm", I become GM, but is no longer possible to use any command. Not even to return to player or as it was before. That would be a bug? Everything indicates when using this command other prefixes would not be recognized, I not understood much what happens.
The image below illustrates what appears by typing and after the press the key "enter" when I'm using the command ".make gm"

Note: Tested with an administrator and player account.
And I noticed is in "commands.dfn" which are things that occurred with the character when we use the command ".make GM". Would use the tag "equipitem" to equip an item or put a mount (horse) on the target selected?? Is this possible?
