has anyone experienced this before?

just went on Roblox 30 minuets ago and i went to play some rivals went on the game and played for a few rounds nothing wired but then when i was playing this round my opponent tuned into a noob like the outfit went from some eboy outfit to the yellow skin blue body noob outfit i thought it was some glitch but then after playing 3-0 i then tuned into a noob outfit for a bit after i finished i turned back to my normal outfit and gone back to the lobby but then i seen other players wearing noob outfits it was wired then i went of the game to the hub menu were all the games are i seen only five games on the menu and one of them were Pokémon brick bronze which i swear to god was not on there any more no pictures just the name it was wired you know so i was just wondering if anyone has had this happening to them before
