Ok, I just released version 2.0.1 which seemed not to cause crashes during my playtesting.
I fully expect this release to be buggy/incomplete/not optimized. I did enough to get the mod working again, but Space Age is too expansive for me to playtest it completely. I'll need help from you guys to let me know of any incompatibilities/crashes you come across!
Lastly, the ammo upgrading feature seems to be broken still. I will try to get it working again in the next update. As of now, turrets will use up all ammo they have before switching to better ammo.
Let me know (in a separate thread) if you come across anything while playing!
