Can't delete a tag
I have a tag attached to 6791 items. I just tried to delete it. After I waited for 35 min Zotero (v. 4.0.29.15) reported an error and asked me to restart. Upon restart I see the same tag attached to the same 6791 items. Is there anything else I can do to get the tag deleted? I'm fine waiting until the 5.0 version if this will be fixed then.
(Adding and removing tags to/from many items is still slower than it could be (e.g., 50 seconds to add a tag to 3500 items). I've created an issue for that.)
