Right clicking the selector for the task icon, presumably as muscle-memory to remove it, caused the following crash. Tested on a fresh game with only base+DLC and this mod enabled. If the icon itself can't actually be blanked out, I'd expect it to reset to default and/or uncheck the "display on map" option.

The mod Mission Tasks - A collaborative TODO list (1.0.5) caused a non-recoverable error.
Please report this error to the mod author.

Additionally (though maybe better as a separate thread), the go-to-location button didn't seem to work. I could select a location fine (though the drag area selector was unexpected) and it would correctly report the surface and coordinates in the task GUI, but clicking on the location would always just send a ping for Nauvis [0,0]. This occurred when the location was set to another planet, but I only actually tested it with the player on Nauvis, so I'm not sure if it would follow that or not.

Hi DarthFreyr,

Right-click crash on the icon selector:
This issue has been fixed in version 1.0.6. It now resets the icon to the default as expected.

Go-to-location button:
As of Factorio 2.0, the Mod API no longer allows opening the map GUI programmatically (e.g., to center it on a specific location). Because of that, the mod can only ping the map, and the player must manually click the ping to navigate to the location. 🙁

Due to a bug, it was always pinging [0,0] on Nauvis.
This has also been fixed in version 1.0.6 — the ping is now correctly sent to the task's location on the appropriate surface.

Let me know if you encounter anything else!
Thanks again for helping improve the mod.
