Thanks Jeremy, but it looks like my problem (Need help troubleshooting TiddlyDesktop version 15) is something different. I just tested release 16 on a different Mac from the one I did my earlier testing on (running the latest Ventura) and I still can’t save tiddlers or create more than 1 new tiddler, or even open the control panel.
I get a mismatch between what is visible in the story river and what is shown in the open tab in the sidebar and with enough effort (attempting to create new tiddlers, renaming and attempting to delete) I can even get a mismatch between what is shown in TiddlyDesktop and the contents of the tiddler folder. Release 14 was fine and, when testing, everything up to prerelease 4 of release 15 was fine but prerelease 4 and onward all showed this very strange behavior with folders, though not with single file wikis.
Cheers,
Dan
