Hello demos, and welcome to Ryandors.
By static blocks, I am assuming you mean like.. spots that you 'bump' into.. as if theres a tree there, but theres really nothing at all?
If so, Id guess theres maybe also spots where you just cant seem to move at all... or sometimes you cant even teleport to a spot, cause the target just disappears when you click it?
If so, your DataPath.cs files needs edited. Maybe you have edited it already, but somthings not right with it anyways.
find the line
Code:
private static string CustomPath = null;
and change it to the client folder holding your new map files.
Code:
private static string CustomPath = @"C:\RunUOClient";
If you havent already done so, make RunUO its own set of *.mul files to read, rather than the ones in the Program Files\Ultima Online install folder.
You wont be able to freeze and melt the statics in game anyways, if you have RunUO and your client both reading off the same folder.
