The mod Circuit Launchable Rockets (1.4.3) caused a non-recoverable error.
Please report this error to the mod author.
Error while running event CircuitLaunchableRockets::on_robot_mined_entity (ID 73) CircuitLaunchableRockets/control.lua:49: attempt to index local 'tbl' (a nil value)
stack traceback: CircuitLaunchableRockets/control.lua:49: in function 'rocketsilo_mined_inner' CircuitLaunchableRockets/control.lua:62: in function <CircuitLaunchableRockets/control.lua:57>
I can't reproduce this bug, but this kind of thing is usually caused by some other mod messing with the rocket silo in ways this mod can't anticipate or control.
Version 1.4.4 should work around this particular error, but I'm not sure because I can't reproduce it.
