I replaced STR_TERROR_MISSION with STR_ALIEN_BASE_ASSAULT in the alienBases section in your save.
If you're using just one platform now (really, don't mix them if you don't know exactly what you're doing)... and still experiencing the issue, your installation might be broken. Try reinstalling the nightly on PC, it does work there. I can't say if it works properly on Android, I haven't used it.
Hello to all, I have the same problem in Android. That's why I can't finish the game, because research already empty. Please, tell me how I can edited save file to open alien base with lobstermans. By your method I open on map two bases, but it replaced an aquatoids and tasoths on first level of assault, so I think it will be on the next level of mission. Please help me with this small problem, I need lobstermans commanders to complete game.
