The mod Just One Last Task - (JOLT) (0.7.0) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event just-one-last-task::jolt_shortcut_open_task_list_window (ID 266)
Unknown sprite "space-location/apia-carnova"
stack traceback:
[C]: in function 'add'

I'm used to this happening when I remove a planet and don't remove the group first, but this happened without even adding the group, and persisted after I removed Apia-Carnova. Please look into it.

I'm also reporting this to the Apia-Carnova developer

Thanks for reporting it, I'm looking into it but don't have a lot spare time so it probably won't get fixed till next Sat, or the one after.

github issue

It should now be fixed in the 0.7.1 bugfix update. It should also no longer crash when you remove mods and it can't find those planet icons anymore. (Instead it will replace them with the "?" icon).

I also made it work when researching Apia-carnova that it adds two groups one for each planet.
