Error: error while running Factorio: exit status 255

This is being executed in A Context, but I've been struggling tonight with behavior parity between "executing in situ" and "manual invocation".

Indeed, it returns an error more often than not, and the CLI mostly picks up whatever error code Factorio binary returned and carries it around. I haven't checked recently but at the time I never found a good way to have a clean exit really.

[AstraLuma]

If the mod indicates it's done, it doesn't matter what the exit code is factorio is, right?

[Palats]

Indeed, that's true - and given that having a meaningful error code from Factorio does not seem to work out, let's ignore it when there is some evidence that the render is done.

Build 0.0.16 changes the behavior for the CLI render command.
