The last fixes are applied in the build I give you.
If you have UO ML installed and you can run it on Linux, open the file located in Scripts/Misc/DataPath.cs and replace the line CustomPath = ""; by the path where you installed UO.
By default it's something like this :
Code:
CustomPath = "/home/your_session_name/.wine/drive_c/Program\ Files/EA\ Games/Ultima\ Online\ Mondain's\ Legacy/";
Check in you Wine directory (menu Wine then Browse C) or go in your home directory and press CTRL+H to show hidden file on Ubuntu and go in the .wine directory. If your are on Kubuntu I think that you have to hit CTRL+.
The error you get is due to a misconfiguration of your DataPath.cs, give it the good path to your UO installation and it will work fine
If you read you're log on RunUO Console :
Code:
tiledata.mul was not found
Make sure your Scripts/Misc/DataPath.cs is properly configured
So configure it and let us know if it work fine
