Error every cycle (non critical) but noticed in logs
```
You cannot call a method on a null-valued expression.
At C:\Users\miner\Desktop\NemosMiner-masterrun\Core.ps1:497 char:41
+     $Variables.BrainJobs.ChildJobs | % {$_.Output.Clear()}
+                                         ~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [], RuntimeException
    + FullyQualifiedErrorId : InvokeMethodOnNull
```

Seems to be related to the $_.Output.Clear() command
