Yeah, it's crashed for me three times now, and yep, back to last save. All three happened while inside my base for whatever reason, and two were definitely the moment I opened a storage chest. Not super sure if I was opening a chest during the third. Hoping for a fix too.

Hi please add if you are seeing this In single player / multi player / peer to peer / dedicated sever . This will help with troubleshooting.

Thanks. :)

Mainly I run into this error when I run past a bunch of trees, attack anything, gather resources (chopping/mining mainly), or open any building (doors, chests, gates, etc.). I think it has to do with fps dropping frames or optimization since we had the last patch update. Not sure what is causing this.

Then in that case, I'll add that my previously mentioned three crashes all happened in single player. And it doesn't insta-freeze, it very briefly seems like the typical roughly 1/3 of a second auto-save lurch. But after that last frame chugs out and things don't immediately go back to normal, nothing ever happens again. Actually makes me wonder if the freezes have something to do with auto-saves. Every single freeze has set me back surprisingly far for how often it feels like the game saves.

Weirdest thing is that after the first freeze, the screen went back to a still frame of my character sitting by the merchant's campfire. But I had left the merchant at least a half hour ago, and probably a good deal longer. That made just about zero sense.

I'm mainly seeing crashes in Multiplayer. Could be my server, but we have 20 people online and not everyone is having the issue.

Same here.

I've been trying to find a fix for this for the last 2 days. Seems to have started after the Feb 26th update but based on my research that isn't the issue.

I had about 60hours of flawless game play over the last week or so and now all of a sudden I get Unity crashes every 15min to 1hr. There doesn't seem to be any correlation to what I'm doing in game to cause the crash but typically results in the game crashing with a Unity error or a full on BSOD. This happens on both SP and MP/Dedicated server.

I've tried:
Windows system file check and repair.
Reinstall the game/clear cache, delete remnant files manually.
Nvidia drivers were up to date, tried experimental drivers.
Changing in game graphics settings.
Deleting appdata files.
Forcing windowed full screen.
Tried Vulcan, causes instant crash on boot.
Tried launching without the steam overlay, tried launching by itself.

All resulting with constant ****ing crashes.

I have the same issue, except it crashes before even loading the game. Just after the intro screen when it bring up a player by a fire, I don't get to choose anything at all, other than don't load/use vulcan. I have made sure that all drivers are up to date, and system reboot and clean, still get the crash.

You may want to check your files and validate them.

This is happening to me aswell, last week over 60h. And now after last updates I can select a character but It'll crash on the loading Screen forcing a total system crash with a blue screen on my system aswell.

I've update Windows, all drivers. I've tried Windowed mode, validate files, administrating rights on start-up, exception rule in antivirus and reinstall but can't play at the moment.

Appreciate the input, but still no luck.
I've also tried:
updating c++ visual studio
forcing settings for physx and v-sync
running as admin
rolling nvidia drivers back to a November stable version with a clean install
and currently looking for try modifying the unity backend itself.

Things I have not tried:
bios modifications(mostly default atm) tailored to the game
complete OS reinstall (probably not going to go through this trouble/downtime)
under clocking cpu/gpu/ram


I've also had a couple crashes while loading into the game after selecting my server. Enter server IP, then password, and crash a couple seconds after.

You are going to want to launch the servers from steam. It's under 'View' in the steam app.

Found a working fix I hope. Been a day and several hours with no crashes.

I ended up disabling Intel Virtualization Tech i was using for emulators and added a slight under clock on my cpu by 100mhz on all cores in my bios.

I'll report back if I start crashing again. But I hope this helps.

No, it worked perfect for over 100 hours game play, then their last update broke it, they need to fix it. The update was the only change on my computer and it broke, I will never nerf my computer to play a game, that isn't a solution, that is just bad programing.

Same here, I love this game to death but I've done almost nothing but crashing every 3-10 more if Odin decides to bless me. I've done everything you've done and then some. So if you've found something please tell me.
