The LlamaServer has now been patched to Version 3.15. Speedy or what?
Happily, as players it is impossible to do anything wrong. You can take your current turns using either 3.14 or 3.15, it doesn't make any difference. Next turn you will have to take using 3.15 - but if you try to open it using 3.14 it won't let you, so again it is impossible to make a mistake.
However, take note if you are playing any non-llamaserver games: The host may not patch immediately, and if you don't have an unpatched version you will be in trouble. So, BEFORE you patch, COPY THE WHOLE DIRECTORY and call it something like Dominions3_14. Then patch the Dominions3 directory. Then you can carry on using your unpatched copy for any unpatched games.
