today whilst playing ssp i was wandering about when i came a accross a huge world glitch there were two giant towers of glass that had spawned with the world and if had just made it does anyone know what this means?oh and by the way this was on 1.9 prerelease 3 that i just got today.when i wend down the glass towers i discovered a stronghold with a silverfish spawner and crystal blox but why where the towers there is it somthing notch secretly added to highlight the location of strongholds?later on i then found crystals and an overlapping mine network and ravine with the stronghold
