Hypixel glitched and the red loading screen appeared. Shortly after the red Mojang reloading screen started blinking more and more rapidly until it was a strobe light of dangerous proportions for anyone with epilepsy. When the game finally fully crashed out, it gave a crash code of "1" and the launcher then crashed. Tried playing single player on a regular world and it did it once more, but has not done it a third time. Cannot recreate for the life of me, cannot determine the original cause.
