So the update is out, I installed it, and it does import my feed successfully.
HOWEVER, and here’s the big “BUT…” — I checked the first event it imported, which is one that had been in the feed previously, and found the number “127” appended to the event name. As in, this event is in my database previous 126 times – which explains why I have 12,000 extraneous events in my Events list. Unfortunately, I can’t bulk edit them, because the filters that might let me do that don’t work with the broken events. And they come up, for some inexplicable reason one to a page, then the page conks out and doesn’t show anymore. And if I do a search, it finds the first one, and none of the other 126… So how do I clean out my database now??
