Guardian Soul did not drop

Ok I’ve been playing this game for over 1000 hours and this is the first time it happens…

I was doing Yoho and we killed her near the edge of the map, some party members got a soul drop and I didn’t.

We killed her a second time and then I got a soul but also the first kill counted as if i got a soul drop on which I didn’t.

I know it’s highly irregular but if it helps the kill happened around 17:30 GMT+3 on Thirain server.
