Those are forms of instability that may exist in an Age. As for how to prevent it, you'll need to Write a stable Age. Or, if playing single-player (or you're the one running a server youu are playing on), you can open up "mystcraft_config.txt" in the config folder of the client (or server), and set the instabilities you want disabled to "false."

Hope that helps.
