Oops, I broke backwards compatibility
V2.2.17 uses a slightly modified trip storage format. If you have a tide or current station selected in your old file, it will not be auto selected in a newer version of DeepZoom. Sorry, but this is a one time upgrade and it wasn’t trivial to maintain backwards compatibility.
To fix this problem, open the trip in DeepZoom. Select the station again, and then resave the trip.
Make sure Include view settings is Yes.
If you’re one of the adventurous few who is actually writing a scripted trip, then you’ll need to manually update the tideOrCurrent entries within the script.
