I was messing around with new parameters in the titleraw command to make a custom scoreboard, and after retyping the same information 4 times and it consistently turning to #'s I came here because I'm fed up. This isn't the first time my commands have been ruined because of this either. Some scoreboard objective names can't be used anymore because they will cause the whole command to turn into #'s, and this has been happening since the 1.16.100 update
