Illager Raids

So, to start, this new snapshot makes it so you cannot jump on to a block right in front of you, and it is messing with all the mobs and the player. What I have also noticed is that mobs can hit you through blocks. For example, I was mining and being chased by a creeper and a zombie, and i built walls around me really quickly because I was low health. The zombie hit and killed me through the wall. I recently encountered an Illager Commander guy with the flag while I was building a wall around my village. I got really excited when I killed him and got a bad omen. I ran into the village and prepared my horse. Anyway, when the Illager beasts got there they were extremely hard to kill because I did not know when they were attacking and I also was being hit through walls. I was on hard mode, mind you. That's all that the bugs I have noticed while playing the new snapshot. I am a little sad because I really like this update but it is still not complete and sadly has bugs. Thanks for your time!
