Hi Hot Hand Harry,
I've experienced the same problems after loading your save #3359: all the saves after I entered part 2 of the Soulforge were corrupt. When I tried to load them, the computer froze and I had to do a reset.
The good news: There is a solution. I've uploaded a working save in a reply to bug tracker entry #2089. I believe it should work on your computer as well. Please let me know.
The, well, other news: I don't know how long it will take before your saves might become corrupt again. Your save is
huge. 340 hours in the game! You have discovered probably all of Nehrim, done most of the quests and acquired a lot of items. To me it looks as if your saves suffer from a bug in the Oblivion engine that is related to saves with a lot of entries. There are a lot of problems with so-called "bloated" saves and a bug called the "Abomb". I am not sure what exactly happened here, but there is a symptom that hints to this kind of bugs: the animations of spells, sliding doors, rising stairs etc. are extremely slow and stuttering.
If you have these slow animations on your computer as well (and I guess it will make it impossible to survive the "Flower" when the stone blocks are moving so unpredictably), you'll have to change a line in oblivion.ini. Make sure you always use the Nehrim launcher. Go to "Settings/Extra". If your ini is still in the standard directory, change its location to "Nehrim directory". Now press the button "Open ini file". The Nehrim directory will be opened, and you'll have to open the oblivion.ini file in there (before that, you can make a copy of the file if you want). Look for the line "fAnimationMult=1.0000". Change it to "fAnimationMult=2.0000". Close and save the ini file. Press "Accept" in the Nehrim launcher (top right, above the button "Reset changes (create-new-INI)".
Now start Nehrim with the launcher. If the menu looks smaller than usual and your saves folder seems to be empty when you want to load a game, quit the game and the launcher. This sometimes happens after changing the ini. Start the launcher again, press "Accept" in "Settings/Extra" again (without opening the ini file this time!) and start the game. Now it should be working. The animations should be smooth again. If you jump down the balcony and press the button in that room after loading your save #3359, you might notice that the stairs now move up nicely instead of stuttering their way up.
So that was the solution for the animation bug. Now how to avoid the corrupt saves? I mainly used the "Perform memory purge now" button. To be on the safe side, I thinned out your character's inventory a bit. Maybe the combination of heavy scripting, animations and a full inventory in the Soulforge is responsible for the bug. So I dropped the extra pieces of the Soulkeeper armor and a lot of food and minor ingredients (I didn't drop any precious ingredients!) I also disabled them via console to make them vanish completely. If you want, you can try to proceed from your save #3359 with your full inventory. I just did that as a precaution.
What you need to do now is to do a memory purge every time before you want to save. Open your inventory, open the EP/LP diary and choose "Settings". "Automatic memory purge" is ON, but that's not enough. You need to press "Perform memory purge now"
immediately every time before you save (regular saves, no quicksaves!). Only save when a fight is over. Make sure all animations are completed (explosions, falling enemies, sliding doors etc. - the "Flower" animations are an exception, you can't wait for them to end of course!) and wait until the battle music has changed back to normal music. Purge the memory, close your inventory and save before even moving your character the slightest bit! That's how I created the save that you can download from the bug tracker. That way you can also create saves in the Flower - on the two unmoving balconies, one at the start and one in the middle of the jumping sequence - to make it easier to get through to the balcony with the button. I hope you'll be able to finish the game now!
