mm if to look date of translations on wiki i think it should be, also based on part of codes i looked think this depends from increasing of alien interest, try to speed up global time and ignore alien ships for 5-6 monthes, me personally waited for 99% of researches till aug 16 2085 until first destroyer ships appeared, for you it can be different.. jan-may 2085 or something like.
Wooooo but... that is a game over for sure. I do it for only one month, and i lose the game.
So, i will play to that moment.
