Replier can only add posts at the end of a thread

[FrederikP]

I'm getting this error on admin panel (4-5 times per day), is this a issue with ElasticSearchEssentials or XenForo?

LogicException: Replier can only add posts at the end of a thread src/XF/Service/Thread/Replier.php:182

This would be unrelated to my add-ons.

I'ld run the "rebuild thread positions" to see if that fixes it. You can do this via the CLI with php cmd.php xf-rebuild:threads --position_rebuild
