Hello all!
I've spent the past week or two helping my girlfriend play through Skyrim: Special Edition and we've hit a bit of a hurdle. To give some context, she's a completionist who'd never played the game before and I've put several thousand hours in (although on PC, so console would help me from time to time when glitches arose), so I was more or less helping her navigate and make the right choices for obtaining all the Xbox achievements.
We got to the point where she needed to level up to 50 for the Master achievement, and level a skill to 100 for the Skill Master achievement. I decided to kill two birds with one stone and went ahead to do the Telekinesis exploit, using Arcana Power from the Dragonborn DLC. I got the Alteration skill to a hundred and made the skill legendary a few times, but I noticed that none of those times culminated in me getting the Skill Master achievement. To further things, my girlfriend also went ahead and finished buying land, then building and furnishing all of her houses for a few more achievements, so we have a lot of progress since then.
I thought maybe the exploit didn't work correctly for the achievement so I leveled up One-Handed (legit) to 100 as it was already pretty high. That didn't seem to help anything. I thought also that the save might have been corrupted or something, so I went back to a very far back save (like several days old) and tried breaking out of Whiterun prison, but that didn't trigger the associated achievement either.
We haven't touched mods the entire playthrough (obviously) and we've been fully connected to internet services so the achievements should have immediately registered. I am beginning to suspect that the issue is either a weird Xbox quirk and it'll resolve in a few days, or we've completely messed up the save to the point where achievements won't register anymore. My girlfriend is really upset about the idea of not being able to finish her goal, so any advice would be greatly appreciated. Thanks!
