The problem is "res[i].auth_address == my_auth_address" in JS code. Dirty test for already "downloadede" optional chat files. Not working when two different users are using same ZeroNet cert. Must use other method to check for already downloaded optional files https://github.com/jaros1/Money-Network/blob/master/js/lib/76-angular-services.js#L5671

Simple workaround. cache without timestamps must be failed fileGet:

                            if (cache_status) {
                                if (cache_status.is_pending) {
                                    // ignore and delete - is being process by an other process - and delete res
                                    res[i].delete = true ;
                                    continue ;
                                }
                                if (!cache_status.timestamps) continue ; // must be a failed fileGet. see next steps
                            }
