I also agree with Zoltan.

Make sure there is/was no out-of-sequence progress on any update.  If due to "over-statused"/"out-of-sequence-progress" maybe this can give you a clue.

Out-of-sequence progress is not necessarily a sin, on the contrary it can speed-up a schedule, it can be an improvement on original plan.  I believe out-of-sequence progress shall always be fixed as soon as it happens in order to keep a clear view of schedule logic.

In any case you shall be in control and understand why it happened.

Good Luck.

Agreed!

Do a float path analysis and follow the path link by link and make sure that it makes sense.

it appears that you have over statused your schedule by doing so something else has taken over the critical path

check your progress again and any constraints
