i accidentally saved at the ending when i defeated gustav with the op ability and now im stuck there and cant go anywhere but watch the cutscene, is there a way to fix this or rollback my data?
Now that you bring it up, I should have disabled the option to save in there. There's a warning to save before it but mistakes can happen.
If the save file is important to you, the best I can offer is that you drop by my Discord (bSCx5fPFsV) and write me a PM with the save and I'll repair it for you.
