Random Stream broken in 5.3?

Hello,

I can not make Random Stream work anymore, even by using stuff that worked fine for many years - I always get a repeating pattern.

Why does this happen - I do not understand. (Something changed from 5.2 to 5.3, and I do not know what.)

I use the actor location to create the initial seed (X+Y+Z), and then grab an integer in range, but it just doesnt work anymore - I always get 0 to 5 in order.
