Very related to this issue (which is still present in this version).

Since vanilla mobs spawn in and immediately turn into Pokémon, I found a random MissingNo in my world. Using spawn eggs was able to show me that it was a Witch that had spawned and turned into it. Something is just wrong with the pool of Pokémon Witches turn into.

It appears this may be because "Hatterene" is misspelled as "hatrene" in the spawn_replacement file for witches. You can try correcting this manually for now via datapack by overwriting the file at data/pixelmon/spawn_replacement/witch.json

Good find! I personally won't be updating anyway due to the overarching vanilla mob issue, but great for others!

I did reply to that other post, but its not an issue; the config option has just been removed in favor of the new datapacking system.

Thank you both! I'll pass this on to Internal to get that typo fixed up real quick!

Cheers!

Edit - just re-read Mike's response. Nevermind ^_^' GJ you two.

Hang on Katzyn! THIS issue isn't solved yet (The missingno witches issue). The typo still exists in code, and without datapacks you can still get MissingNo, which isn't intended.

Mike is referring to the issue I linked originally, relating to general vanilla mob spawning, which (according to him) isn't an issue. The witch issue still remains.

Yepyep gotcha. I'll pass it on now~
