So Helios stating before you research it something completely different to what it states after you research it is ‘too subtle’. There’s a difference between one vehicle inclusive and one vehicle exclusive.
See above Vivisection reply, it quite clearly does nothing.
Every Haven assault has been at a strength of 30. If Project Domovoy did what it claims prior to researching it, which is roughly a 20% reduction in the strength of their attacks, at least some of the attacks on sites protected from mist would be at 24 - but no either these consistent attacks increased in strength at an exact value when completing this research to render it pointless (which is a fancy mechanism to make the research do nothing) or the research simply does nothing.
Without rehashing the point again, same applies for Walls of Jericho. The bug may be present for that because I stole it rather than ally with Jericho, but none the less it has made no change.
The flight speed one is hard to gauge I’ll grant that - but the in game stats of the aircraft have not changed, and the fact even with that upgrade, and all the other defensive upgrades, havens are assaulted and die before I can get halfway across a continent shows they’ve either allowed themselves to starve and have no defense, or this upgrade has as the in game stats would indicate - done nothing, or it all works, and the game is just poorly designed to make havens impractical to keep alive. I’ve got a little short of 1 aircraft per continent (Australia is on it’s own) which I’d think should be plenty to defend them. Either way, there is a problem here that needs to be addressed.
