Slightly other crash, but im catch it after upgrade mod too ^.^

Thanks everyone! I'll work on a fix!

The issue was a mixture of how wayward seas adds its content, as well as an alternative tile buildability description. Hopefully that should of fixed it, and the ordering of the two mods should not make a difference. Although Slipstacks mod may break with this, and wayward seas, as they modify its tile buildability rules, which might occur after the cultivator is made. Fair warning. There's nothing I can do about that as all of Wayward seas occurs after the data stage.

Similar error with a few different details

Its very confusing to me why people are putting plants that have no minable field in them, but apparently they are, just updated my mod to handle that too! Sorry about these issues everyone, it is always difficult to be able to predict what issues other mods will bring up =-) But the mod is better for it now haha

still error with different lua but now variations instead of minable

And the latest update should now ignore those trees with no graphics/variations, haha thanks! Looking through the code I am confident that that is the last issue we have with that for now. Please let me know if there is a particular plant from another mod that is not working as expected (missing graphics etc) so I can see how they made it and accomodate accordingly.

famous last words but i wish you luck none the less
