Hi @riogrande,
We made changes and installed a new version of wpDiscuz. Please don't delete it until new update available that does not have this problem. We tested several times (also during the test, your users also left comments) and it looks like the problem is fixed.
In case that the problem appears again, please let us know.
In future you may have a problem with caches as we detected not clear deleting of cache files. We'd recommend to check all caching plugins and key plan of those, it seems that conflict with each other. After deleting, we don't see changes in the dashboard. Somehow it does some hard caches which are not being updated after the simple updating of the cache. In case if there are problems in the future, please make sure are totaled deleted cache files.
