I also have had various areas of task names disappear on one of my project files. all other logic and task info is still there, the name just shows as blank. We store files on SharePoint, but I was using a copy on my computer hard drive. I can restore a previous version, but I’d like to know what I can do to prevent this from happening again in the future. currently, it’s happened to two people, each using different files/project schedules. Both were 2500+ task schedules. We use Project 2016, ethernet connections to our network, in the USA. Filters were all cleared too.
