Sadly the mod is dead :(
Was looking forward to V.3.0 tbh

I got into contact with the SMA team on April 20th 2019.

Because of the amount of people involved in making SMA in the first place, not enough are still around/active/able to keep working on it and the team split. I was able to get into contact with a few of them including BlazenChambeR himself, who has since quit A3, and essentially the permissions from all the people involved would not be able to be obtained means that the mod will never continue mainline work, nor be able to be donated/used by any other mod teams, no matter how reputable.

He gave permission for maintenance, config patches and other such support, but not anything involving modifying/taking SMA files themselves, and SMA is for all intents and purposes halted/cancelled.

As of April 2019, if you want to keep SMA more compatible with other mods into the future, optional configs include the following-
