Automatically earned achievements based on behests done in 1.0?

I might've frightened the party I was in just now by unlocking two or three of the guildhest achievements at the same time by jumping into my first guildhest on a Legacy alt I moved to a non-Legacy server (so I could play with some friends). Actually, it kind of scared me, to be honest.

My active character isn't the Legacy character in question, just for the record.

But yeah, the short version goes that I had a WHM alt I capped after 2.0 launched. I abandoned it for a while because of transfer restrictions (friends were on a non-Legacy server). When the transfer restrictions were lifted, I decided to move it (along with my old Legacy main) to the server my friends were on. Bored, I decided to pick the WHM alt back up the other night (for a change in perspective, if nothing else). I realized that I needed to raise ARC to prepare for BLM (I hadn't leveled the class in 1.0 due to different requirements), and figured a guildhest would speed things up after doing some questing.

Then, as soon as the guildhest ended, BAM! Serving a Greater Cause II and III suddenly unlocked. I'd done a number of behests in 1.0 (but not any guildhests in 2.0 until now), so that's my only theory as to why this happened.

So did the game actually keep track of the amount of behests I did in 1.0 or something? Did anyone else with a Legacy character unlock multiple guildhest achievements after their first guildhest (and possibly freaked out a little when it happened)?

EDIT 1: Okay, so after double-checking the numbers, the Achievement progress for IV says 21/30, so I had 20 completions recorded before that run. Meaning I either did 20 behests in 1.0 and I coincidentally stopped on a heck of a number, or something glitched. Haven't decided which yet.

EDIT 2: Okay game. Getting really tired of your shenanigans.

Just did it to me again, this time with guildleves when I went out to Hawthorne Hut to unlock the levequests out there to round ARC to 15. Just got All the More Region to Level IV and V. The progress on VI says 232/500.

Did they really have to retain the stats from 1.0? I mean, it's nice and all and I normally wouldn't mind, but when there's a guy standing literally five feet away from you when this happens, it gets incredibly awkward to the point where you just wanna get out of there ASAP.

If you exceded the requirment to recieve an achievement prior to acquiring it, you will acquire it on the next successful completion of a requirement that counts tward it, and yes 1.0 counts twards them were strongly requested by the forum posters. If it really bothers you, there is the option of a new character.

Awkwardness felt asside it really doesnt matter rewards through achievements are glamour in nature.
