When updating the P_BirdsClose_Circling to a new engine version (4.12.5 or higher) the particle system breaks.

Steps to Reproduce
  1. Convert attached project to engine version 4.12.5 or later

When the project opens notice that some of the birds flap their wings incorrectly and are facing the wrong direction in some cases.

The P_BirdsClose_Circling particle system is unchanged.
