Windows Game no longer loads.

B_Unicorn · Friday at 11:02 AM

Yesterday while playing on the current stable build i would randomly get the on screen logs pop up with errors but all would be ok once i had closed it down. I just kept playing and didn't really think much of it, i know stupid of me.
Then today i wanted to try the new chicken coop experimental version and switched, loaded the game up, changed a couple of minor sandbox settings, jar return and infection rate lowered.
Continued saved game and it wont load past the Initializing world, Configuring splatmaps the screen logs pop up with errors and it wont load.
So i reverted back to the current stable build and same keeps happening.
I have no idea what's going on and now cannot play..... Help!

You have some corrupted regions in that world. Sadly something still happening too often in the game. You can go to where these listed files are and delete the ones mentioned and it should let you load in again, but do note anything in those regions will reset to its default state. So if your base is in one of them, it'll be gone/reset to default POI. Just an FYI. Try deleting the r.0.1.7rg file.

Code:

You have a broken region file. Normally you should use the region reset command to fix region problems (rr help in the console to see how to use it), but that probably won't work if you can't fully open the save. So you'll have to go to your saves folder for that map and find your region files. Most likely, at least one of them has a file size of 0. Delete it and start your save. However, be aware that whatever region(s) are deleted in this way will revert to their original state from the beginning of the game... if there are bases or anything else built in that region, it'll all be gone. If you are lucky, it won't be where your base is. If it is, you can either start your base and storage over or else start a new save. The game makes backups, but if you load the save again after it's broken, the backup will also have the same broken save, so at this point, you've already loaded it again and your backup won't help.

In the future, be aware that errors in the console can be a serious issue. Don't just load the game again... make sure you have your own backup of the save first that will hopefully not be broken. Regular backups of your saves can also save you from losing an entire save. But that doesn't help you now.

Thanks so much for your help, deleting the r.0.1.7rg file. worked and thankfully my base is still here

I am super grateful as i have well over 200 hours in this game so far and wouldn't want to start again.
