#34 Deleting flow folder deletes category & orphans flows

[Troy Hawkins]

I wanted to delete all the processes under a certain category and similarly the associated valuable substance flows to reduce the size of my database. I tried to do this by "removing" the "folder" from the window at the left side of the screen. This resulted in the removal of that category and the flows no longer appear in OpenLCA (except when I perform a search and find them) but they have not been removed from the database flows table. However, now the category is removed and there isn't an easy way to delete them permanently. When I search and find them and then try to open them, OpenLCA shows an exception error and slows way down/freezes up.
