Odd behaviour, as i never had the problem before and the plugin loads in previous sessions.
you mean that the plugins, inserted on previously existing sessions files, loads fine? but trying to add a new they just doesn't show up on VST plug-in discovery/selection?
if that's so, try first to backup your ~/.u-he directory, where you installed your U-he plug-ins, and start re-installing one by one from scratch on a new and empty ~/.u-he directory; on each install, test whether the VST discovery process is successful, by showing up on listing, one at a time; if none appears still, then it's some other VST plugin, not from u-he, that is crashing the discovery process too early: you'll have to investigate which one is the culprit, by starting over from ~/.vst contents perhaps.
