Ok, so I just got the mobile version after hearing it introduced hardmode (but even better, allowed health to go above 200. Yes, that was higher on my priority list). I made a new world and played on it with my sister, who is new to Terraria. We were having fun, until we fought the EoW, and I found out that there were no Demon Altars in the only Corruption chasm in the only Corruption in the world. I found two more lying around in the Corruption, but once I dug a path to access them, they disappeared (they were inside of a chest, or Shadow Orb, or Ebonstone, or something like that). I found only two more Altars; one in the Underground Jungle and another by Spawn, as always. I want to keep one for crafting, but I am pretty screwed once I enter hardmode, and all I can do is just make a new world and smash those. Just wanted to get my thoughts out, and see if anyone could make sense of it.
