I had to migrate to the beta version because version 4.21 and 4.20 had a regression in the system of replication of physical objects but that was solved in version 4.22 and now I face another problem 
The problem is that it is impossible to return the project from the previous version to 4.21 or 20 (blueprint, materials and level) now I should expect an update for correction in the directional light and his shadows.
