Game Dev 3 Final Project duelist spawning

The duelist spawns on the right after running any playthrough of a game dev 3 level, when you press edit level or win. Is this an easter egg, or a bug?

X 78 Y 41, and he spawns during testing the level, and it happens on the one where you can share the link as well

I have been recently having the same problem. Does anyone know why???@nick???

I fixed it by setting the player template to not exist.
