I need help on multiplayer

I accidentally deleted the thirdpersoncharacter from the map, then pressed undo, but after that when starting the multiplayer, the first player is displayed normally, and the rest of the players are spheres that can fly in the air. How to assign my thirdperson to other players
Help me please

Is this a local multiplayer game (as opposed to networked)? How did you place the characters, did you just manually place the character blueprints onto the map? Do you mean you accidentally deleted the character mesh? If so double check that the pointer to the character mesh you deleted didn’t become stale in the character blueprint when you deleted him… Go to your “Character Blueprint > Components”. Then select “Component List > Mesh” and in “Details” check that Skeletal mesh variable still has your character mesh assigned to it.
