Openhab 2.5.3 - problems recently with switch items....going OFF after sending ON and vice-versa

Ive had exactly this problem (But nothing to do with ZWave)… like a rule is being double processed. My full post with my rules etc is below.

My only solution was to downgrade to the previous version.

Im glad its not just me thats seen this behavior, though Ive been unable to narrow it down to what exactly would be the reason (rule processing engine etc). All I can be sure of, is its not my rules, as they have worked fine on X previous versions and work fine again after downgrading.
