Hello dear developers! Today I want to share this problem - I built a house whose floor consists of half blocks of cobblestones and stands on columns two blocks high, when I ran away from the mobs and ran into the house, then for some reason the spider was under the house was able to damage me and even kill me through the half block. I lost several levels of experience because of this spider. I will be very grateful if you fix this error. Why is it a mistake? Because it started with Snipshot 20w13b. in early versions, I didn't notice this. Thank you for reading this text, I hope that you can fix this problem, and I will continue to play your wonderful game! <3
