Is google doing some sort of testing or they won't think the link from normal webpage that important anymore ? Please help me if anyone have an answer
Every day, google is updating one thing or the other, don't worry it will be fine soon, just continue your SEO work bro.
Not now, but in past I have seen it to many sites. It is temporary & you will get your links back in few days.
Yes its normal for google to go abnormal to show you less backlinks or move you in lower ranks in searches , it generally corrects in a couple of days.
It can fluctuate over time. Don`t take it seriously! Important thing is have you seen any drop in rankings?
