With Alpha 18.1 (b something) - Map size issues on Dedi?

[Cadamier]

Hello,

 

I was wondering if anyone was having issues generating maps larger than 8k on a Dedi? This is without the map mod... Every time I tried generating one bigger the server would start but wouldn't generate a map no matter how long I waited. I know it was a while ago, but still wondering. I've got an 8K map but its an island which I don't care for and I'm trying to stay away from Nitrogen at the moment.
