ArgumentException when loading custom map

So I modded a precudural map with the rust editor i loaded it vie +levelurl and got THIS:
"ArgumentException: Offset and length were out of bounds for the array or count is greater than the number of elements from index to the end of the source collection."

I have no idea what went wrong

https://www.dropbox.com/s/e3v6rhl3ilfsnhw/proceduralmap.5500.1055198752.189.map?dl=0

this is the map, I "know" that you have to change the 0 to 1 at the end if you want to use it on a server

I'm getting this error as well then i get this error

Plugins: Couldn't open advapi32, error: advapi32: cannot open shared object file: No such file or directory

Then server does not boot 

Tried resaving the map in a updated version of Rustedit and still getting the same error.

Please help!!

Merged post

Max custom map size now works correctly: 4096. We need 6000...

When I start server with a map size of 5500, it send error: ArgumentException: Offset and length were out of bounds for the array or count is greater than the number of elements from index to the end of the source collection.

After stage "Loading map", server start flood this error, fix it pls
