I notice something weird today, I have 7 rigs on a determined Riggroup, When I'm at the rig list all 7 are online and runing and none has restarted for at least 24hours. Then on the RigGroup menu its really unstable, sometimes I have 6 of 7 rigs online and then it goes back to normal 7 of 7, only a refresh later and then I get 5 of 7... Is that instability normal?
