Created Issue:
Spawn egg in item frame causing Chunk reset
So yeah, I found and partially fixed the issue I was having! YAY! Turns out, I was right, it was one of the Spawn Eggs in the Item Frames I had hung on the wall of my base that was causing that Chunk to reset. Now, don't ask which one, because I didn't exactly check to see which one it was. Although, now that I know this, you can work on fully fixing the problem straight on. So, thanks for being so patient with me, this has been really hard for me as well. Rockatoa, Brickticks out!

Cannot confirm.
First of all, I don't know what spawn egg it was,
second, it was inside the chunk,
third yes, and
fourth, no.
I only know it wasn't any of the following spawn eggs:
Horse, Sheep, Llama, Chicken, Pig, Cow, Ocelot, Wolf, and Parrot, as those also exist in that chunk, but they don't cause the reset.
However, there were some others that are in an adjacent chunk but don't cause this effect in that chunk, those include
Creeper, Skeleton, Zombie, Spider, Endermite, Guardian, Shulker, Polar bear, Wither Skeleton, Stray, Husk, and the formally existent undefined spawn egg.
Other than that, it would be down to any of the 1.12.2 spawn eggs that were not listed above.
My advice, try loading up my world save, (I know you have it, I sent you multiple bug reports with it in them), in 1.12.2, and assigned all the still possible spawn eggs to individual chunks, (try placing four of them around a block suspended by a fence post), and check to see which one disappears when upgrading to 1.13 pre-release 5, (if using the method above, then load up in 1.12.2 and upgrade again, but only with the four spawn eggs in item frames as test subjects, each in it's own chunk).
Hope this helps. Rockatoa, Brickticks out!
Mod edit:Formatted wall of text
Please attach the launcher_log.txt after upgrading your world from 1.12 to 1.13-pre5
Can confirm with an enderman spawn egg. Added a world download and the launcher log.
