In the early Alphas build planetary invasion was unlocked very early in the tch tree. In the new alpha I noticed its now a much later unlock (rightly so to in my opinion). However last night I'm sure I researched the tech that lead to planetary invasion but I cant find it as a researchable item.
Has it been reomved from the alpha? At the moment I have a massive armada surrounding my enemies planets but no way to invade.
