WebAnno versions since 3.5.0 exhibit a bug that can lead to
annotations being deleted when a user tries to view a document
from multiple browser windows, tabs, or computers or when
another situation occurs where WebAnno detects an access to a
document while it is being edited (aka concurrent access).

This bug is fixed in the WebAnno 3.6.7 release.

Upgrade to WebAnno 3.6.7 to improve the safety of your data!

No software is bug-free, so please make regular backups!

Either perform system level backups including backups of the
database used by WebAnno - or at least regularly export your
projects and keep these exported projects as backups.
