Hi guys,

This should be resolved now. We made some changes to the API and upgraded the version of our core technology that we use to merge annotations, and there was a regression in that new version which caused this issue. We rolled back that upgrade and will investigate further.

I apologize for this - we’ll make sure to add a test for this so it doesn’t happen in the future.

Thanks!  
Logan
