Just lost entire base - chunk appears to have reset back to its default

[MrPlowjoy]

Not much more to add. Holed up on the top of a POI, with bedroll down (70+ days).

Left to hand in to the trader, came back and noticed that cars and trees that had been cleared had returned. Sinking feeling...base gone. POI was back to its default, although the link of spikes I'd laid across the top of the base remained there, floating above.

Be really wary, everyone. Total loss, no coming back from that now. Tried reloading the save multiple times, no difference.

Edit: Screenshot. Shows the layer of spikes that were atop the base built. Nothing else of the base remains, POI has reset back to its default state.

Edit: Nailed it. The bug is because a quest item had been placed in the POI, even though a bedroll was down and had been down for quite some time. See screenshot that shows a quest bag in the POI, even though the only active quest was 200m away (top right).

It has something to do with constant updating I guess, we should appreciate that. I even noticed a small download earlier, like 4/5mb, maybe some small hidden updates sometimes ?

[MrPlowjoy]

No update inbetween, last update to the game was about 6 hours ago my time. Nothing after I closed the client.

On one of my saves I have holes in the map (navezgane), textures have disappeared. Do not get too attached to your progression for the moment, we will see a lot of updates in a relatively short time I think.

Yup. Stepped onto that rake far too many times myself.
The most effective, the best approach to do there is to:
1. Do save achiving. Create a new archive every time you stop playing, so, even if your save ends up corrupted after you close the game - you'd still have access to your *.bak files. And you need access to the *.bak files, because everytime you launch the save, those files are rewritten. If you happen to have a corrupted main file, you'll kill your *.bak files by launching the save.
2. If you have a suspicion that your save file might be corrupted(after a blackout/game crash/PC crash) - you need to refrain from launching that save until you make a backup of it. After that, you can try and launch it to see if everything is okay. if something went wrong - you can always restore core file from their corresponding *.bak files.

You should get attached to them.. but only if you can afford doing the chore of backing them up everytime it is.
Minecraft had the exact same issue, previously. Hope TFP would figure out a way to report suspicious save structure and would suggest the player to automatically restore it from the *.bak files. That would make the save ressurrection a way more friendly to people who can't just spend hours to figure out and fiddle with data files of their saves.

Wouldn't have helped with the most recent issue though, without losing hours of progress. Been DIYing through the day, so pop back to the PC occasionally to have another go but to lose half a day of progress and go back to the prior save would also be quite frustrating.

I only stepped in because of A20, think its better to leave it for a while. Thanks for the affirmation of it being a legit problem though.

Please take a look at the Pinned Troubleshooting thread for workarounds and fixes. If you still have an issue, then please read the Pinned thread on How to Report an Issue, and follow the instructions.

If you are on a20 experimental, be sure to wipe all data from previous versions and try a new map with a new seed you have not used previously.

Also, build your base away from town and POIs... I built my base from scratch against the side of a hill. Also, can a dev confirm that a base protection block would prevent that issue of stuff getting deleted/reset?

Bedroll is already supposed to prevent POI reset.

But yeah, building a base away from POIs is all well and good but I'm on Survival, with 50% loot, 75% player block damage, 150% zed block damage, 300% blood moon zed block damage and running zeds. Can't whip up a base strong enough against that, without enough time to prepare.

In A19, the POI reset boogeyman only seemed to me to affect POIs that are useable for quests. There were several remnant POIs that could only be returned to default by entering console commands to forcibly reset chunks.

Because of the sweeping changes brought on by the tile system that the Pimps brought us in A20, my paranoia about losing bases to POI reset has returned and I built my permanent homebase from scratch, well away from any POI.

My horde bases, OTOH, I feel less concern for due to reasons we all understand, and these get built anywhere that fits the need. In the most recent update for Experimental, I lost a horde base that I had build out of one of the new remnants and it happened on day 42. Much fun was had?
