OH1 rules die after OH2 was running`?

EDIT: issue is different after analysis… please ignore this thread

I have a really mystery problem…
I have OH1 and also OH2 on a Pi2.

my standard installation is OH1 which I shutdown when I want to test a little with OH2.

It happened now multiple times to me … after testing around I startup OH1 again…
-> rules model is loaded at startup but NO rules at all are triggered

Anybody would have an idea what happens?

did you reboot your pi2 or did you simply shutdown OH2 and start OH1?
