This is not the save I need. I have already completed those quests that you have. I requested a full save in the game of the latest version of the game. There the last task was
Kill the huge boss in the cave.
What huge boss do you mean? Dicc the Impaler which is that big Ogre (orckind) boss in fallen fortress on western side of Sybaris?
If so, he was added several versions ago. The only new thing added in 8.3.0 was one location a little to the east of Coastal fortress - just a little away from fallen fortress itself. There is not much there right now - only your typical orckind camp - no quests or such tied to it right now. There is no boss or any cave.
Also, my save-file which I provided earlier is from the latest version. Or, to be more precise, its the save-file from 7.1.0 which I ported to every version since. It does work and there is not a single error while loading/playing it at the latest version of the game 8.3.0.
But hey, I did kill that boss for you in this save-file (its the same save-file from earlier I just went there and killed that boss).
With some pics with Dicc the impaler and his defeat. Along with the new location that was added.
The only reason I did not kill that boss, yet, is that there will be some quests (probably) tied and such to it so I left it be for now. That boss and content tied to it is clearly not finished yet.
