Greetings,
i played the witcher enhanced edition several times since i first downloaded it but this time i am facing a game breaking problem that i never experienced before.

After hours of gaming, suddenly all my items in inventory disappear and i can't loot any monster / crate as their loot seems to be empty. The game is mod-free, tried to re-install many times but nothing to do.

I tried to open my last savefile with TWeditor (enhanced version of course) and it seems that all items are actually listed in inventory tab; also savefile appear not to be corrupt. If i try to start a new game, there's even a chance i won't get the two potions from vesemir during prologue. If i receive any item, it will obviously be some random items with a random template (i.e. a club, a random potion, a sapphire...)

So i tried to open the game through djinnii adventure editor and looking at logs, it seems like there is some sort of texture problem showing when i try to loot / dragging any items.

Please, anyone can tell me how to fix this?

Put your save file up somewhere and let somebody look at it. It may be corrupt (even though your editors are reading it).

here's the file http://www.mediafire.com/file/qtw5wfazleargpg/000011_-_Swamp_Forest-011.TheWitcherSave/file

but, as i said, i have the same problem even if i start a new game...

Right. I can open your save, and the inventory is filled with many items. But you are cheating, isn't it? So your installation may be corrupt after all that cheating - or can't read your cheat-saves. Seems to be a typical pebcak-case...

Thanks for your reply.

As i mentioned in the first post, i tried to open savefile to verify the content of my inventory at first, then i tried to add / delete items to see if - by any chance - the situation restored itself.

I've been trying to fix it for the last two days and having no much left to try i downloaded some mod to see if inventory / baseitems related scripts would somehow work as a fix.

The cheating part came late, trying to fix the problem.
As i said, reinstalling the game and starting a new play gave me the same error in the prologue, when you're supposed to receive from vesemir to different potion (again, no mod, no cheat)

Look at this, for example: a brand new save, from a brand new installation without any previous save

Since you're obviously starting a new game (from the above), uninstall again and *delete* any Witcher folder that may remain, and *delete* (after backing up) you saves folder, that way you will start from absolute fresh. Now reinstall and *do not* use cheats or save editors, they will corrupt your saves... eventually.

I did this many time, plus, i tried to switch compatibility mode to vista and then xp, installed directX 9.0c standalone, checked folder permissions and installed in a random folder outside ProgramFiles. Nothing.

After 4 or 5 tries the problem randomly disappeared.

Unfortunately after few hours of game it seems the problem has occurred again.

Same story: open the game, load last save, and inventory empty.
So i tried again to start a new game but this time i went deeper launching the game through the adventure editor and looked closer at the log, i found this error:

"
Object template it_potion_001 [type 2025 - UTI ] doesn't exist.
That was right after Vesemir gave me Swallow and Thunder potions.
If i try to open the inventory instead i get this error from logs:

DragSlot Empty Item Update - zglosic Danielowi :)
If i try to drag any item from the inventory slot (and i can't actually) i get this:

ERROR in CDragSlot:ChangeTexture()
I can't honestly understand why i got all this problem after years of linear, bug-free gaming on the witcher 1 ...

UPDATE:
i also bought this game on steam, same problem. I think maybe the problem is with windows 10, but again, this is the first time i am experiencing this

You may be right. Even though this is the first time, it doesn't mean it's not Win 10 and its 'game-unfriendly' updates.
