Expect to be ignored if you ignore this template.

What happens:

When I launch my custom Modpack with the new updated version of EnderIo that was released yesterday that I get an error message telling me bad File = Capacitor_machines.xml

Error Message 'key' 'enderio:block_stirling_generator/burntime' is invalid.

What you expected to happen:

Some kind of way to fix it as I have no clue and I try removing the Capacitor_machine.xml and that did nothing.

You have an old copy of the file capacitor_machines.xml in your user recipes. This is a file the modpack author (you!) created. Fix it,
