Hi thanks. After a few hours debugging, it seems to be the Story node in globals.lsf got damaged. This value is a long string and I don't have the mean to decrypt this. I successfully recovered by copying this value from another save file. Everything is working except the waypoints, which are inaccessible now and everytime i load the game, there is a "tampered or damaged" save file notification. Please help me to ask for the way to decrypt the above value as well as the mean to remove the "tampered or damaged" notification
Edit: found the code to decrypt here https://github.com/Norbyte/lslib/blob/master/ConverterApp/OsirisPane.cs.
Trying to see where is the problem.
