I am using MS Word and the Zotero plugin in macOS (10.15). Recently I noticed a bug - after working with track changes for a while, word will not save the file. Trying 'save as' does not help, a new file does not form. I can copy-paste the text to a new file, but then the tracked changes are lost. This only goes away if I restart word, but then all the chnages are discarded. Any ideas??
