Hello,

 

i would like to start a new Playthrough with TBC. Will my save be destroyed by upcoming TBC-Updates?

So far Obsidian hasn't released a single update which wouldn't allow you to load an old save. 

However, balance might change drastically breaking your builds. It all depends how much the system will change.

Hey everyone,

 

While we plan to eventually take Turn-Based Mode out of Beta and update it with fixes, we don't plan to push anything that might break saves.  Granted, with a game this big and with so many features anything can happen, but we will try to be as safe as possible when it comes to the fixes.

 

Thanks for the help with Turn-Based Mode, and I hope you enjoy it!
