Critical error. Field [groupid] is not integer

[LenR]

I started getting this error today, looks like I have about 7 hosts out of 460+ that are broken.

Any ideas? I can't even get to the screen to delete them?

I'm on 1.8.10, it looks like a mass update to "replace hosts groups" caused the error. I was able to do another mass update "New host group" to get them back.

I wonder if this is a bug or a db error locally?
