When I open console to enter command (using slash [/] button) and try to paste something from clipboard by pressing [Ctrl]+[V], console shows previous command. Оnly after I press [Ctrl]+[V] second time, clipboard contents will be inserted into it.
Example:
/teleport + [Ctrl]+[V] (coordinates are in clipboard) => /teleport + <wrong numbers>
After I delete those wrong numbers (using [Backspace] button) and paste from clipboard again, its data will be inserted properly.
