Ok question for ya...

Is it my imagination or are soul fragment collection event fragments now different than the achievement soul fragments?

Was going through the misc fragments to convert the junk ones and realised I have significant amounts of both Lucifer and Dark Lilith. Operating under the premise that a soul fragment is a soul fragment and there is only one type of fragment per soul/character I went and looked at the achievement page. And then went what?? cause the fragments from the event and those on the achievement look completely different.

So the subsequent questions are:
If you don't get it in the event convert the fragments cause they are worthless and aren't going to be reused in achievements or another collection event.
Hold on to them because they might have another event with those fragments eventually.

Thoughts?
