For the last month or two I have more or less only played ESO, yet all night Project Spark achievements have been randomly unlocking, with the achievements dated 15/11/14.
I know for a fact I haven't earned these achievements, though the dates do match up from the last time I played the game (although it was only for 10 or so mins). I'm getting achievements such as "Critic's choice award" unlocking - have an 80% rating across all words. I haven't ever played anything in Project Spark other than the very first part and like i said, it was only for 10mins a year or so ago. A lot of other Project Spark achievements on the progression bars, whilst not unlocked are more or less filling up too.
What's happening here? Has my account been hacked, is it a glitch in the system or what? Everything else on my account looks secure as far as I can tell. Also, apologies if this isn't the correct forum.
