Love using Residence. Thank you. I just accidentally clicked the Backup flag in a resadmin menu, and tried to drag it away before releasing the click. I'm not sure if that behaviour contributed to this bug.
The server followed with the following log lines, after which I right-clicked the Backup flag to ensure it was false. After that, the server crashed and became unbound :-D haha, damn! Thanks for staying on top of so many 1.13 bug reports.
