Is there anyway to stop this from happening while remeshing?
Because your model is not closed
Is there a way to make it so it doesn’t do that?
Is there a way to fix that?
You could use quad remesher or if you dont have that
The remesher in dyntopo @ bottom should work i think
If you already made the remesh permanent and saved it for some reason, you can try use the facegroup function to separate out the funky part then use hide&delete tools for it. Its a bit complicated uh
