The mod Landfill plus (1.0.7) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event Landfill_plus::on_tick (ID 0)
LuaTile API call when LuaTile was invalid.
stack traceback:
[C]: in function 'index'
__Landfill_plus/control.lua:132: in function <Landfill_plus/control.lua:104>

Error occurs when in Navigation Satellite view and clicking "View Surface". Chance of this happening is about 50% for any planet. Error does not occur when actually landing on a planet, only when clicking on view surface for the first time.
Thanks

Thanks for reporting the bug.
I couldn't replicate the issue but if it is what I am guessing then it should be fixed in version 1.0.8. If you still get the error just tell me.
Have a good day!

Thanks for checking. Unfortunately the error still persists after the update. I should add that the only mods I am running are Space Exploration v0.5.37 + minimum dependencies and Landfill plus. Using a fresh map or migrated map seems to make no difference.

Ok I finally found out what the problem was. It is now fixed in version 1.0.9.
Have a good day!

Updated landfill plus to v1.0.9. Viewed 20 surfaces and can no longer reproduce error. Thanks for the quick fix! Have a good day
