wtf does these errors mean
 

Ok, i go to generate the map for an overworld, and when i do it, it hits a certain level, and it gives me this error:

I get this error when i close out the graal exe from the error above:

No help?, :(

I think the first one is when you try and make a map and the levels arent fully linked! Second one I have on odd times, I think it just runs incorrectly and needs to be closed!
