So I upgraded Lemmy to v0.18.0. However, this version seems to be more unstable. Unfortunately, I fucked up and didn’t backup the database so I can’t revert to the previous version. Next time it happens, I’ll try to hack together some automation to catch a crash and automatically recover. Hopefully this holds until the devs can push an actual fix.
Also, fwiw, I’ve figured out a fix. I forgot I changed some other shit that was actually borking it.
