When Beacon Fuel was introduced we auto fuelled all beacons for 6 months. This was released as part of Release 167 on 21st June. So the auto fuelled beacons will not expire until ~21st December.
We auto fuelled the beacons because it was a new mechanic that hadn’t been explained to players who had already placed beacons. They didn’t know that their beacons might have expired next time they signed in. Maybe 6 months was too long. But we were attempting to do the right thing for all players.
I’m sorry that your build has been regenerated - because it looked really beautiful.
We’re updating fuel again to better control the duration of beacons new player can create. This will mean that new players who only put in a couple of hours can’t easily create beacons that are fuelled for 6 months.
That said, we also need to make sure that the game is open to players who don’t play every day or even every week. Not everyone play schedule is the same.
Maintaining, iterating and migrating a live environment is actually a big challenge. It would be waaaaay easier if we wiped the worlds with every release which is what would happen if the game wasn’t developed whilst in Early Access. (This isn’t a complaint - rather just describing the extra challenges and efforts we put in to maintain the universe whilst still developing it.) As it would be required after 1.0 I think it’s important we get good at it before 1.0!!
I hope you create something new and even more awesome.
