Evoker Seed Trouble

[X-x-TheMayor-x-X]

So I have been attempting to get the Evoker related trophies and used the two seeds provided in the trophy guide. At first, I thought hmm I will just spawn in, set the difficulty to peaceful, and build up a little base around the mansion and then attack the Evoker when I am good and ready. So I did this, once I was geared up with some iron armor and sword I set the difficulty back up to Easy so enemies will spawn and could not find an Evoker anywhere in the mansion. Later I read that the Evokers won't respawn, so switching from Easy->Peaceful->Easy in essence despawns them. No problem, says I, I'll just fire up this seed again and give it another shot without changing the difficulty. This time, the mansion will not spawn in at all, for both seeds I have tried. Anyone else experience this problem?

This problem eventually went away for me if anyone else was having this issue. Reloading the seed from the guide eventually spawned the mansion as expected after several regens of the world
