found an issue with this mod - it will prevent the vanilla artillery tech from being available. after many trial and errors, it narrowed it down to this mod. removed all mods, art tech is there, enable just this mod and art tech is not available. thus blocking any artillery tech from being researched. it also appears just removing mod, doesn't bring back artillery tech in saved games, leaving them broke as far as I can tell.

I'm having the same problem. it sux cause I may have to restart just to get artillery

kind of moot now, that space age is out but the work around is using console commands and forcing it to enable artillery tech. must be done every time game is loaded.
