I’m sometimes having problems that seem similar to Mike’s. I sometimes think not all actions are applied. Not sure if it’s a bug in PLEG, or just in the complex logic I’ve created :-o
And since I’m not sure, I assume it’s me, for the time being 
If I have some evidence of a bug, I’ll post it.
I have got a problem with my Vera, i think my firmware is corrupted, it has stopped working alltogether. I am waiting for a replacement, once that is set up i will monitor my PLEGs to see if the problem is still there. I am hoping that my problems were caused by that.
