Friendlist bugged

Somehow if your friend was onliine 5 mins ago, it sometimes shows 1h ago or 6h ago. I noticed this too when your friend is online in game but no in friendlist.

I noticed similar thing today but in clan list. Like we were chating in cln chat, i went afk (switched tabs) for not more then 2-3minutes, came back and saw that person was offline for 13 minutes. so..

This has been a bug for ages now, live with it.
