Hi... I was going to play a game with my friends red vs blue then when I got there I cant see my character after several rounds.What am I gonna do/ Shall do?

You won't spawn unless you joined a team.
You need to ask them to restart the game (type /moludrome again or w/e the command is) in order for you to join a team

(unless you're talking about something else like #battle)

i could not see my mouse when i went to utility
