Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - Bugs & Technical Problems Certain Achievements not Working

Hi there. I just finished my first play through of DOS2 - Definitive Edition. I played on "Classic" mode with no mods.

Across the play through, 61 achievements have popped. However, some that I know I have completed haven't.

Specifically: "Back to School" (enter the academy), "Andabata" (become champion of the driftwood arena), "Get in the Ring" (enter the arena of the one) and some others such as "Chosen" and "Serious Academic"

Two of these are apparently "unmissable", but they haven't popped. Not sure what's going on. I thought they might pop when I finished the game, but seemingly not.

Any suggestions?

The achievements themselves should be working. Perhaps Steam/Galaxy was offline or otherwise having issues when you should have unlocked them?
A couple people reported achievements not unlocking until restarting Steam, or the next day (before they got around to any troubleshooting), but a temporary glitch like that wouldn't still affect most of the achievements you mentioned.

I did wonder about that, but the same session that I should have unlocked the Academy achievements, the "Wreck of the Titan" achievement unlocked.
