Pillagers don't spawn near outpost

Pillagers don;t spawn near outpost. I had bad omen farm and when I run minecraft at 1.16 Pre-Release 1 it stops working I waited because I'd get another version of this. We have 1.16.2 Pre-Release 1 and still don't appear.  My world is so broken but i had problem only with this. ( I started this world in 20w14a and it worked all the time)
