A recent model has "hole" in the roof, where a group of points seems to have been lowered / misaligned. Is there a way to find the source of the error, e.g. a misaligned image, and fix it?

That looks like a metal roof. My work has noticed similar problems with metal rooftops.
I suspect maybe reflective spots in the photos.
Best answer
Reflections, lack of textures. Share the dataset if you can, it can be used for future research efforts to improve the software in a future release

Rooftop is matte, checked images for reflections / glare and didn't find any. Good idea, though.

WebODM Backup? Where would you like me to send it?
OP
~4GB
You can post a link here (google drive ,dropbox, or some other file sharing site)
what was your processing setting? fast / default / high res?
OP
Optionen: auto-boundary:true, pc-quality:high, mesh-octree-depth:12, mesh-size:300000, dsm:true, dtm:true, dem-resolution:2, orthophoto-resolution:1.0, use-3dmesh:true
check, and what about min-num-features (integer) ?
OP
Default: 10000
Maybe you can try and increase this value, for example to 15000. Although it's also interesting to see the individual image on this location. If you can post / copy one of this? And what was your overlap? Did you fly nadir or oblique?
OP
OP
Building modeling, I usually fly oblique circle(s) and another nadir pass. Mini 5 Pro, just it's usually freehand. See image above
OP
Will re-run with 15000 and check.
OP
Dataset is uploading to dronedb

Same error with 15000
mmm I cant download the complete images folder, only indidividual images. Is that something you can edit?
OP
Hm, seems like you need to have a subscription to mass download. Will check with DDB
I'm getting:
