How I discovered this bug

I first discovered this bug on July 15, 2021 in Minecraft 1.18 Experimental Snapshot 1, when I was first trying to check out Minecraft 1.18's new mountains. I used seed 0 ("creashaks organzine") because I considered it to be kind of ubiquitous. However, when I used /locatebiome to locate the nearest Snowy Slopes biome and teleport there, my game crashed.

I was just about to create a bug report of my own when I discovered this one.

I have done some testing with this bug

The object listed in the exception "dfw" is only called that in snapshot 21w37a, it's called "dfk" in 1.18 Experimental Snapshot 1, "dfn" in Experimental Snapshot 5, "dfq" in Experimental Snapshot 7, "dha" in 21w39a, and "dhi" in 21w40a. According to a previous comment by the user "ampolive", the name changed because the obfuscation map changed.

I have concluded that this crash occurs when trying to generate grove, snowy slopes, jagged peaks, frozen peaks, and stony peaks biomes. When testing these biomes, I set my render distance and simulation distance to 2 as to make sure the chunks being generated were only those of the biome I was looking at.

I have attached all of my crash reports where the game crashed this way.

edit: it is inaccessible let me add the links

I hope this information is useful!

WHY was this marked as resolved? My minecraft PE is updated to 1.1.2 and still doesn't work properly??? I know I'm using the command correctly, I've been using it since they added the fill command.

Same error on my iPhone 7. Which is sad since I'm a creative builder and the commands make it so much easier when working on big projects.
