I'm not good at English.
Don't worry because your world will not become glitched. Glitch Entity can spawn naturally. Glitch Entity can attack you. Glitched Entity will send strange messages in the chatbox. Glitched Entity can put Glitched Blocks in your world (not the glitched pumpkin in Minecraft) (You could mine those Glitched Blocks). Glitched Entity can't respawn like Error Entity. And I want to say that Glitched Entity is almost like the Pigmans Maybe this mod will not be updated anymore, I don't have so much idea for this mod.
