It's rather odd how they pulled this off. ElementFilter.lua does something like

if self._values.difficulty_normal and diff == "normal" then return true end
if self._values.difficulty_hard and diff == "hard then return true end
...
return false

It's not completely trivial, but in my opinion the easiest fix (though not most elegant) would have been something at the end, before the false return. Something like

local use_dw = self._values.difficulty_easy_wish==nil and diff == "easy_wish" or self._values.difficulty_sm_wish and diff == "sm_wish"
if use_dw and is_difficulty_overkill_290 then return true end

More elegant would have been an automated tool to just add true entries for those difficulties whenever DW is true. But they seem to have done it all manually.

Good find! I've extended my script to try attaching "_husk" to all existing paths to automatically handle this in the future. And the hashlist is updated too.

The hashlist file that comes with the Bundle Modder is 30 MB. I expect people will continue using the Bundle Modder to extract files. So I provide an alternate hashlist file where the unnecessary lines are removed.

http://pastebin.com/RCgSKS1X I cannot put everything in a single pastebin anymore and thus will move new files elsewhere; I'd rather post an entire functional hashlist instead of pieces of new entries. To keep the hashlist small I will probably keep only entries that are actually used by the game (pathnames and some dialogs that I am aware of).

I've updated my mission script dump.

Have you checked endianess? When the bundle modder says "37cba50a84a9919b", it means 0x9b91a9840aa5cb3. When I say "1737b67c90f18939", I mean 0x1737b67c90f18939.

The Lua is compiled and encrypted. I am not sure about the encryption key or how to decompile.

One of the remaining textures (1737b67c90f18939 big endian) clearly belongs to "units/payday2_cash/safes/grunt/pattern/", so feel free to bruteforce it.

I think I hit the cap. 52 files left. Apart from the render_template_database, I am certain that both the textures and the material_configs are never referenced by the game. In fact there are 100 or so unreferenced files, so it already took some educated guesses to get this low.

The Lua dump happened to have the paths for the missing Lua files. So there are 17 material_configs that are probably not used, 70 textures that I am not sure about, and e87b6f708d8270f2.render_template_database. That last one should be located either in the folder "shaders/" or in "core/shaders/" but I cannot find a hit.

Ah, I meant very simplistic attacks that need add just 1 word. But to be honest, I believe these remaining material_configs are truly not used at all. The textures are of greater interest.
