EI!Harkos

A little later, after the incident with Shadow Ancient, I decided to try it on the oldest version of this mod, when it was still called “Eternal Isles”.
What I expected is not clear, because in the very first version there was nothing from the components of the totem. Why? Because crystallized stone, creeper stone, and infernal rock are dimension blocks that were added in the mod for version 1.7.10, and the first version of the mod was for version 1.7.2. Because of this, I had to radically change it - I replaced the creeper stone with a Precasia stone, I changed the infernal rock to the Abyss stone, I replaced the crystallized stone with a Mysterium stone, I replaced the damage amplifier with a tentacle, and the lamps with purple glowstones.
After building a totem in creative, I switched my mode to survival and started playing. Let the beginning be exactly the same as with the discovery of Shadow Ancient, everything else is different. I could not find mysticism in any way, but I found strange moments, the evidence of which, unfortunately, was lost (later you will find out why):
Grass turned black
For a fraction of a second, the boss's health bar was shown without a name
Blocks appeared with a well-known unloaded texture
I thought that since the mod was in active development, such mistakes could well be allowed. And believing in this, I thought that I would not stumble upon anything mystical in this mod... Until one moment.
I already had diamond armor then, and defeated the dragon of the End. At first I just survived as I was supposed to, but later I discovered something. It was some kind of mob that had a player model. I thought it was some kind of NPC and ran to find out what he was selling. But as soon as I tried to interact with him, the boss's health bar appeared, which was called "Harkos". This name seemed familiar to me, and when he began to attack me, having examined his texture in a better way, I realized that I was not mistaken. Harkos is a dastopia boss from Advent of Ascension that many on this wiki would refer to as the "evil Observer".
I tried to fight him. His behavior was extremely strange: to hit me, he jumped, also, to confuse me, he ran around me, after which he hit. Naturally, with this behavior, I found a lot of bugs. From freezing Harkos for 5 seconds, to a “mega-jump”, which consisted in the fact that he jumped and, having developed tremendous speed, flew away to the nearest mountain.
When I defeated him, the game froze. Later, the screen went white and a window popped up saying that the Minecraft app was not responding. After that, I could not enter Minecraft. After checking what happened, I found a sad picture: half of all files were either deleted or damaged, which was especially reflected in the screenshots, because they were impossible to see.
What we have?
*Harkos under development (+ his clumsy texture spoke about this).
*An extremely strangely made script that kills Minecraft.
But the strangest thing is that in the “crash-reports” folder there was a text file indicating an error, but it was in the contents.
