Solved, had multiple trailing commas in the JSON.
It's happening again, but not because I used the retail version of desecratedzones.json this time. 😆
App Version: 1.5.0
D2RHUD Version: 1.2.0
Issue: JSON parse error popup upon trying to enter a game (or open the automap) with a TZ eligible character
Details: After choosing a difficulty to enter a game I get this popup repeatedly and have to spam close it to get through the load screen and into the game, ditto when I open the automap for the first time.
I don't see any obvious issues like typos or missing brackets/commas or anything in my desecratedzones.json, I used the updated files that you linked here:

It worked fine until I changed the existing zones (which was an edit that previously worked when the 2.4 TZs were first added), then I get this popup.
