I get this error when loading a save after the latest update:

The mod Compact circuits (0.0.8) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event compaktcircuit::on_configuration_changed
compaktcircuit/scripts/processor.lua:494: bad argument #1 of 2 to 'pairs' (table expected, got nil)
stack traceback:
[C]: in function 'pairs'
compaktcircuit/scripts/processor.lua:494: in function <compaktcircuit/scripts/processor.lua:490>

Sorry, should be fixed in 0.09
Thanks for reporting

yep it works now, thank you for the quick fix and awesome mod!
