Hi I'm new here (and in the Minecraft in general) and I couldn't find an answer to one thing that bothers me. 1. Lava mechanics. As I understand when water flows over lava it should turn into an obsidian, however on this server it turns into a cobblestone. Why? 2. Can I build a nether portal anywhere in the Overworld? Or is it blocked on this server for some reason? I'm asking because so far the only way to reach the Nether I found is by warp. But there's one portal only and the area around is heavily mined already, so I couldn't find any Nether quartz for example.
