My base wasn't even unfair. It was just more clever than they were apparently. :P
Or the day switched over before you checked it. The memory for replays only lasts about a day from what I have seen.
Sometimes there is a pretty big delay so you can find this replay later.
Could be block, ofc, but I think it's more likely that it is some sort of a bug. The replay station is full of them.
Also, people have different view on what's fair/unfair, on blocked tombs, bug usage, meta playstyles and tons other aspects. If someone doesn't like your base that much they don't want to face your creations ever again it doesn't mean that someone is not clever enough.
I was currently playing when one of my newly reactivated outposts gained 5 deaths. Outpost stats showed (+5) deaths but no new raids, and no replay showed up.
Restarted, waited and hour and restarted again, still no replay.
I mean, it's the counterpart to the '0 death 0 genmat' replays who's deaths vanish into the ether, so it kinda balances in a way. Maybe it's those raids catching up with itself?
I think something similar was reported if you ; Crash, Close the app, Alt f4 or Block someone.
could be any honestly.
Hmm, I didn't use any bugs or exploits. And I incorporate the tombs into the path they take through the base so they can't miss it, and I don't even put any traps there because I want them to get the tomb.
It's just... a base with some insidiously placed traps that kill them from a direction they weren't expecting, and a couple of holo cube surprises.
I don't follow any metas. The most "meta" thing I use is a neat trick I discovered. Where you make them come face to face with an armored warmonger, and then have two more armored warmongers nearby with bloodlust. When the average player kills the first one, the other two show up and become a 1-2 combo. When the player breaks the first one's armor and staggers it, the second one leaps through it and kills the player. An unusual amount of players fall for this every time.
