Why after updating the game did my world revert back 300 days?

Hi there, and thank you for reaching out. My name is Aileen, and I am an Independent Advisor here to give you guidance. Before we dive deeper, could you confirm what game this is? Based on your description, it sounds like Minecraft, but I want to make sure.

Let me know what game this is and if it was part of a recent major update or preview build—that might help clarify further.

ok found the world save files copied them. Uninstalled and re-installed Minecraft for windows 10. After installing and updating created a new world, after 10 minutes of playing the game crashed while digging dirt. So this is the 3rd instance of the game
crashing while mining/digging... I would say in total in the last 3 days my game has crashed probably close to 300 times.

Unfortunately this did not work for me. I reverted to the KB4497935 update and still I get the error on admin approval required games(third party games). Not sure, but after days and days of talking to tech support, researching on the internet and trying
fixes that I would think would help, I got nothing. Maybe its just best to wait and see if an update will come through in the next week or so as I would really like to play Metro, as well as Tyranny.

EDIT: Ok, so after reverting to the previously mentioned update, then re-installing the KB4053293 update, it started working again. Not sure how or why this happened, but it did. Of course, I have only tried to dl tyranny so far, but I am now starting metro
to see if it worked. So, in conclusion, maybe try reverting and reinstalling update and see what happens?

Yeah, did all that last night and all cam back OK.

I reset my router a few weeks back and the NAT was open but then after a couple of days it reverted back to Moderate. Lets hope with the setup I have done it stays like that?

Did you recently download an update or just change to 12?

My tenure of 8 dissappeared just as it was going from 7 to 8. I'm not sure why but just after I did an update it was gone. The update happened literally the same day it was due to change. About a month later it came back after a new update.
