Mar volt 86 megtekintesem az uj csatornamon youtubeon az egyik videora. Nos ma ez lecsokkent hirtelen 47-re. Mi tortent?

It's normal now. They used to leave views they couldn't validate for quality purposes alone UNTIL a video reached around 300 views - then they might no longer include certain views in the count (such as your own, repeats, short views, etc.). NOW they can validate views dynamically, at any time, even at lower view counts. So view counts may fluctuate or even pause, at any time, even at lower view counts.
