That’s some great testing/feedback. I hope Ethan sees that.

A human sees the errors immediately but fixing still takes time. One would prioritize getting a working prototype out before polishing away such issues. Rationally, it’s more important to get feedback on the mechanics and such than making sure the models and collisions are good.

I believe you are right that a human wouldn’t make at least some of these errors. But I think one needs some experience with 3D modelling software or alpha stage games to really be confident about what errors humans plausibly make.
