installed plugins do not get assigned..
sorry for the title... its hard to summarize
i used Ardour Ardour-5.8.0-x86_64 on an Debian 9 installation.
I now installed Ardour-5.10.0-x86_64 and Debian testing on my new laptop.
in some old projects i used the IR reverb plugin. if i load old project on the new installation ardour says that the plugin is not found. but the plugin is installed (at the same location as on the old installation (/usr/lib/lv2/ir.lv2/)) and i can select the plugin in ardour. but all IR plugins that where already saved in the project are not working (just that dummy plugin)
i could just delete the dummy IR plugin and add it again. but then i would loose all the plugin settings.
