Achievement-based unlocks glitch after reset

[Velorien]

1) If you reset unlocks, counter-based unlocks (which are awarded with the corresponding achievements) do not reset, so you can't re-unlock them. I'm not sure if this is true for all of them, but it's certainly true for Pyromancer.

2) I reset achievements, and after three kills my first new character instantly unlocked Reaver. The achievement lists 7187/1000 humanoids killed, so it probably loaded the counter from my pre-reset game.

Apparently resetting unlocks AND achievements still doesn't reset Pyromancer.

Seems like achieving the pyromancer or cryomancer while in easymode also doesn't unlock them. I've been playing for a longtime and never got them due to this. Any chance you could add a check for the achieve on save load?
