No, such changes are not retroactive on old saves.
Optimisation will continue throughout early access.
We know Crate are working on a 5th tier of housing so that will probably bring new buildings to support that; wouldn’t be a weekly release of one building though.
If their is no solution for old saves, then why do we play?
It is the same as not saving any progress at all, because with every update you need to start again.
Also, the herb patches on the map, where kicked in the water by the flattening tool and it’s currently not possible to undo the flattening.
Just stop playing till the full release is ready- we’re still in Early Access. If you’re a person who finds it hard to play a game with bugs then really you need to wait. I don’t meant to sound rude but your complaints are beginning to feel a little spammy x
This is REALLY early access. As such it will probably take many restarts, do overs etc. I don’t think, although of course it would be nice, that you can come into a game at this stage and expect not to lose your build at least sometimes. Of course they are working on fixes…but sometimes the solutions don’t work with the past.
