Back in 1.8. I remember that all too well. Scariest part about this mod, is that nowhere is safe. I remember that they could literally teleport inside your house. They did that to me on many occasions. Absolutely terrifying.
This mod is awesome, EXCEPT once the angels start spawning, they don't stop spawning. My world was OVERRUN with angels. I could traverse the Nether without being invisible (I also had on the Artifacts mod which had an invisibility scarf).
One t'ime i was playing my world with mos weeping alngels and one of them touches me and teleports me to a dimension and i cant get out so i lost my world
