Sales are dramatically decreasing - what's going on?

My sales decreased almost to 1 order/day (maybe to zero in next days). I checked other Level 2 sellers and even Top sellers, and I noticed that many of them delivered fewer orders than 2-4 days ago. Also I saw that these days Fiverr made some changes on them interface (for example they had some problems with some non-clickable gigs, in default search was set first the "High Rating" category, but now it was replaced by "Recommended" category; and Fiverr staff added the "Recently Viewed" category).

New opinions and suggestions are welcome. Thanks in advance!
