Steps to reproduce:
1. Create a new world.
2. Summon a mob, or use /entitydata on an existing one so "NoAI" NBT tag is set to 1.
3. Use /tp with relative coordinates to make it face a different direction than the default.
4. Leave the world and open it back
5. The mobs should be rotated to a set direction... It fixes to the previous position if you use "/tp @e[r=1] ~ ~ ~ ~ ~" on them (using the selectors you want of course)
PS: If you can't reproduce it first time, maybe you just left it on the same direction it gets rotated because of the bug.

That's a solution. But it's not very handy if you have to do that command every time you get back on that world. And besides, it's just a bug, isn't it?

No, not a bug. Working by design.

And what's the point of that? That just makes me have to rerotate the mobs each time I enter the map. I made them stupid (and moveless with that) for a reason... I don't want them facing another direction as the one I set them...

Again:
Mobs don't serialize their orientation
Read: There is no function for the mobs to store and load their rotation. That's something which must be added to the game - which makes this and the duplicated MC-61587 a feature request --> Minecraft Suggestions on Reddit.

"There is no function for the mobs to store and load their rotation."
What kind of an idiotic comment is that? EVERY living (and some non-living) entity's NBT data contains a 'Rotation' tag/compound containing 2 values. This is saved to file and even used real-time while the world is loaded. You can do /entitydata @e {Rotation:[0.0f,0.0f]} to change the rotation value of every loaded entity in the world. Normal entities which use this tag also seem to load it instantly when loading a world, and be looking the right direction, but NoAI mobs don't.

Not fixed in 1.8, or the feature has not been implemented. Would be nice for 1.8.1! 😉
