Yes, you could update to the latest version by redownloading the mod package from the opening post, and go through all the steps again, as if the mod was installed for the first time.
There would be only a few things to take care of in regards to compatibility with saves from older versions:
- if Odin was already unlocked in one of the previous versions, he would still randomly appear at the beginning of battles. If that's the case, I would recommend disabling Odin by using
Hyne Save editor to prevent him from appearing, as in the newest version, Odin is summoned by using an item instead.
- there might be something strange in GF Ability lists, like "Tool-RF, required AP: 53/30". This is because some of the Abilities have been changed or swapped around in the latest version and can be easily fixed by selecting the Ability, then doing a battle. The issue will auto-correct itself afterwards, and the Ability in question will be fully learned.
You could also just send me your save game and I would adjust it for you, but I think it's better to wait until the next version of this mod releases within the next couple of days.
