Was afk, don't really have any info other than the report:

The mod Compakt circuits (2.0.10) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event compaktcircuit::on_tick (ID 0)
action index out of bounds: 40 > 2.
stack traceback:
[C]: in function 'set_undo_tag'
compaktcircuit/scripts/processor.lua:1766: in function <compaktcircuit/scripts/processor.lua:1753>

Are you in a multiplayer game ?

Thanks for report. Should be fixed in 2.0.11
