Wall Dimmer Associations don't work

[Gorilla]

I have two ZME_05468 Zwave.me wall dimmer sets and a razberry running on 2.0.1-RC33 and an everspring switch EVR_AN1572.
I want the following setup:
- a single tap or press and hold on any dimmer will switch or dim both dimmers
- a double tap on any dimmer will switch the everspring switch

All that worked before I upgraded to the new razberry firmware last year to 2.x.
Now, the zway software has much improved, but this basic functionality still doesn't work.
I reassociated and reincluded the devices many times, the function then works at most once.
Strange behavior. I can't see anything useful in the logs.
I just update to each new release candidate to see if it works but it seems the firmware on razberry has a problem.
Wish I could downgrade...

You can downgrade, but may loose your present configuration

It turned out I had to power cycle the wall dimmers to make it work again. Guess there is bug in the firmware (1.8).
