With just a cursory look at the bugged anniversary achievements, so far it appears that in 5.0.3:
Expert Phase-Smith, Perfect Templar
- Solar Lance, Deploy Fenix and Purifier Beam will no longer fail the achievement.
You must defend additional pylons
- Losing structures during the end-game cinematic will no longer fail the achievement.
Big Spear Diplomacy
- Using Reconstruction Beam will no longer fail the achievement.
- The achievement triggers have been altered, but in a way that’s a little beyond my editor knowledge. But, hopefully the recoding will award the achievement more consistently and without the need to additionally kill something else after Narud is defeated. However, it’s not apparent if Raven Auto Turrets are counted or not in awarding the achievement. (They are technically classified as structures.)
