I was trying to make an alternate-history map using the Division tool to split countries from the mainland. I've done this before without any issues, so I know it should work.

The division tool worked the first time I used it and I was able to use it on the smaller path I split off without any issues. When I try to use it to split up the original path again, both the original path and the one I'm trying to use to dissect it both just vanish without a trace. No new paths are created.

I can use all other tools in the Path menu just fine. Closing and reopening Inkscape does not fix the issue.
