Can't get seed schedule to work.

[charliemagee]

Have schedule chosen under Run>seed_behavior
Have seeds in Keyframes>seed_schedule: 0: (607585776), 12:(3751926681), 24:(4241381034).

Have tried with nothing in the seed, -1 as seed, and the same seed as in frame 0 on the schedule: 607585776.

Doesn't seem to be doing anything.
