Game crashed when I opened the calculator. I had opened it previously on the same save, without the crash, and had not added any new mods since doing so (solar calc was the most recent mod added to this save). Crash was consistently repeatable upon reloading the autosave: every time I open the calc after reloading the save, it crashes again.

The mod Solar Calculator (0.5.52) caused a non-recoverable error.
Please report this error to the mod author.
