Hi,You can update to 2.39 because you have nothing to lose. Everything that was critical was already fixed with CMI 2.6.3.
Only XtMasterSlave plugin took a hit and there's no replacement for it and nobody is currently working on it to fix it.
You can also choose to update to 2.37 and use the previous CMI 2.6.2 release for a while longer since that is known to be stable and everything still works perfectly fine. But dlc that require 2.38 won't be supported so you can't stay on 2.37 forever. As a new player you won't even know what the changes are. It's the old players that get annoyed when kiss decides to make changes to the code that hasn't been touched in many many years and destroy legacy plugins in the process.
I just came back as of lately into the game. My last build was on COM3D2-v1.55. I think.
The reason it took me so long to come back was remembering how complicated it was to run around for files and examples/explanations to build a decent English translated and modded setup. Your guide and modpack make it so much simpler. I want to thank you for your time centralizing a big part of this information.
With COM3D2-v2.39, is it possible for me to use my old saves? I don't have my old setup files anymore but got the Ultimate 2023 + updates.
