Issue description:

When I set the PRC to output the substrate to a logistic pipe connecting to a chest so I can, you know, keep producing power, the PRC just infinitely outputs substrate. I don't know how it's coded at all, but my guess is that the substrate in the output slot is not getting deleted when it sends it through the pipe.

Steps to reproduce:

1.Connect PRC to a basic or advanced logistical transporter
2.Place a chest at the end of the transporter
3.Set the PRC to output items in the right slot

I keep getting the

log spam too, here's a link to the debug.log:

I found a message in the logs that might help:

[22Mar2020 22:47:31.000] [Server thread/WARN] [Mekanism/]: An inventory's returned content count does not line up with InvStack's prediction.

This error repeats many times.

EDIT: Sorry, I did not see that it was closed for being a duplicate before sending this message.

That is fine, and that log message will probably help. I plan to look at it some point before the next alpha, though it will be a bit as I am in the middle of rewriting our energy system.

Just want to thank you for posting a detailed issue with specifically relevant logs. Reports like this make our job so much easier.
