When trying to use this mod with the Thruster Control Behavior mod by Quezler, there is the following assert and failure to load:
diurnal-dynamics/data-updates.lua:4: attempt to index field 'surface_properties' (a nil value)

Traceback:
diurnal-dynamics/data-updates.lua:4: in main chunk

If you believe this issue is on their end let me know and I'll report it there. :) Thanks for all the hard work making awesome mods.

Also seeing this with Space Platform Graveyard by Quezler. Starting to wonder if they do something odd that's causing this? I'll report it over there as well.

I can and will fix this on my end! Thank you for the report. Should be fixed in 15 mins.

If you're curious, it's because I'm assuming that planets all have surface properties, I thought it was a mandatory field...

Turns out it's not and that mod is adding a new planet called thruster-control-behavior that does not have any properties.

Thank you! Fix confirmed, looks like things are working now. :)
