Patch notes are imported from steam. There may be errors. This mostly exists so I can stay on top of them to update the features in our tags and scoring categories (which I do manually), but since many of you liked the idea of staying up to date with all the games in one place I'm working on making this data automated (right now I manually hit it every couple days) with better info and linking in with the game views.

There will be more data and proper atribution here (original author, steam link, original post date, etc) real soon, I promise. This is just like a technical test to see if they're coming in ok at all.

The Binding of Isaac: Rebirth » Welcome back to the Isaac Online Alpha!

Welcome back to the Isaac Online BetaAlpha! We have some bug fixes and game improvements ready for you all!

As mentioned last time, this is a Beta Alpha, so not all planned features and game modes are available right now. We also STRONGLY RECOMMEND that all players participating in the Beta Alpha make backup copies of your save data files in a safe folder. For those who have made backups but lost their progress marks, the steps to get your back is at the end of this post.

Where to report bugs:
Subject line: #IsaacOnlineBeta 1.9.5

You can message me on twitter, but send bug ports to the email above with the subject above please

Include the version number in your subject line, in the exact format listed above. This is very important for us to filter and keep track of the most current issues. The version number can be found on the title screen, main menu, online menu, lobby screen and in-game pause menu. It’s everywhere now 🙂

If you encounter a crash, your crash log files are extremely helpful for us to diagnose the issue. Here’s where to find them.

In a file explorer window, navigate to Documents>My Games>Binding of Isaac Repentance>crash_dumps

There are 2 files for each crash, A DMP file and a TXT file. Attach both of these to your email and our developer wizards will be very happy.”

Lost Completion Marks
Here are the steps that should help in restoring your missing Completion Marks, if this issue has affected you.
Step 1: Have your save file backups handy! Hopefully you heeded our advice in the Online Beta announcement post to make save file backups before joining the Beta, because without them, this method will not work.

Step 2: In your Steam library, right click on The Binding of Isaac and open the ‘Properties’ window

Step 3: On the ‘General’ Properties tab, click on the ‘Steam Cloud’ switch to temporarily disable the Steam Cloud function.

Step 4: Open the folder where your active Binding of Isaac save files are kept. Take the backup save file you want to use, and copy it into this folder. Rename this file “persistentgamedata1.dat” for it to take the place of your slot 1 save. For save slots 2 and 3, copy backup saves to this folder and rename them “persistentgamedata2.dat” and “persistentgamedata3.dat”, respectively.

Step 5: Next, launch the game. At the save file select screen, you should now see your backup save files restored, and when you go to the character select screen, you should see your Completion Marks restored as well.

Step 6: Close the game, then open the ‘Properties” window again, and click the Steam Cloud switch again to turn the Steam Cloud function back on.

Step 7: Launch the game again. Steam should notify you that the Steam Cloud files and local files do not match, and will prompt you to proceed with either the local files or the cloud files. Choose ‘local files’, and the backup saves you just copied will overwrite the Steam Cloud files.

From there, the game should again function normally, with your Completion Marks restored.
