Weird crash when splitting a way

[rickmastfan67]

Was doing some editing work adding in a new highway bypass that a friend alerted me to and when I tried to split ways to add in a bridge, JOSM crashed for an unknown reason when splitting the way (via the "p" button).

Whatever happened, it corrupted my save file when I hit the save button afterwards. Went back to the auto-saved version from right before the crash and was able to open it, but if I re-saved it, JOSM wouldn't open it then. It throws up this message when trying to open it:

Could not read file <file name here>.
Error is:
Relation with external id '1,593,688' refers to a missing primitive with external id '-4,310'.

But I was able to redownload the area and just copy over the new ways that I had done so far (from the auto-saved file that worked) and some minor fixes and was able to continue. :)

Anyways, I can't seem to duplicate this at all, but I still thought I would post here just in case you can figure out what happened here.
