Synchronized timed moving objects become UN-synchronized after a few minutes

I am currently working on a platformer - and a big deal is synchronized platforms that move back and forth on a timer…

I have noticed At first my platforms are completely in Sync - and after I walk around a bit in a different part of the level - and come back - the platforms are out of sync…

They run on a looping timeline - and begin on “event begin play” - wondering what could be causing something like this?

Any Suggestions?

Can you post the BP Code?

Do they Run on the same timeline?
