I encountered a crash that I think has to do with the mass driver. I tried updating Factorio (from 2.0.42 to 2.0.43) to see if that would fix it, but that triggered another crash when loading the save. Here's the error message when trying to load the save after updating Factorio:
The mod Lunar Landings (1.1.7) caused a non-recoverable error.
Please report this error to the mod author.

Here's the error message related to the mass driver. If it's relevant, I'm using the "set requests" option on the mass driver requester, set with a circuit that subtracts everything in the logistic network from a constant combinator.
