I'd like to add to this. Unfortunately mine is a little more extreme than losing previously awarded achievements. I only just noticed that I never received a lot of my achievements when the achievements system went live. I'll give a few examples: On my main I've collected almost all the datacrons. I have the codex entries to show I got them but when I look at the locations section of my achievements all the planets listed don't have them marked off. As all of my toons have passed the starting planets I would need to make new ones just to get those ones! I've also completed most flash points and some Ops and again on the listing for FPs and Ops there is no record. When the system went live I thought it I had to complete them again to get the achievements, I then found out last night that a friend of mine that barely raided before the system came out and never did after the achievements came out, has the achievements listed from when he used to raid before the system went live. This was true for everything else like datacron finds, etc. I contacted customer support to try and get them reinstated but was told it was a bug and needed a bug report and hopefully!!!! would be fixed in the future. Hence why I am here. I'm not very hopeful for this as the system has been out for ages, and if it hasn't been fixed by now I doubt it will ever be. I mean one of my toons heads still poke through his rode when flying on a speeder, if that's not fixed I doubt this will be!! Here is hoping.
