i know that this might be a bit of necro, but if your still having the issue of it relizing it needs to update but closing the conection to the server, i resolved this after a mess around, so i coppied the client folder to the desktop, with the game version as 1, i then edited some tilling in my project that is still in the rpg m os folder, then changed its game version to 2, also changing its extension version to 2, i test the rpg m os folders client, and it works, i can see the tiles i just edited, i also add 2.txt to the extensions folder and add this comand to it:
:dir
C:/Documents and Settings/User/Desktop/2112 with rmx-os/RMX-OS Client/Data
Data
then i launch the client i copied to my desktop that is still at version 1, it updates it and allows the game to launch, i can see the tiles i edited.
obviously i got:
C:/Documents and Settings/User/Desktop/2112 with rmx-os/RMX-OS Client/Data
from the location of folder that im using to apply the update so it will vary depending wheres yours is, i hope this is some help to who ever it may concern
