For some reason I get the feeling that your mobs keep spawning near me while I'm not looking. For example I'm in the nether, just building a bridge, and suddenly I'm getting f###ed by a Baphomet from behind. I'm pretty sure I should have seen it if it was there beforehand, and this has happened on multiple occasions. Is that intended? I don't have a problem with hard mobs, but it would really be better imho if you could prepare in advance, and not just suddenly have them ambush you while you're in a disadvantageous situation.
