I have added in the downloads section the 1.6 mod version created for the 1.86 with all the DLC.
Remember the 1.86 continues being installed in the ..\My Games\Ironclad Games\Sins of a Solar Empire Rebellion\Mods-Rebellion v1.85\..
The main change at this version are the compiled files and it increases the performance a lot. Specially loading the maps and more. Remember reload your LAA. At least by the moment, you must use it. In the future, if the 1.87 is released, the LAA will be integrated in the game and you will not need it again with your mods.
