How to determine at what level missed the soap

A guide for those who want to get the "Don't drop it" achievement and after beating the game don't remember at what level they forgot to touch the soap

directly the essence

Problem:
Soap has been found on most levels, but it is not known which ones are missing. Replaying the entire game for an achievement is not an option.
Solution:
Alt+Tab game, locate folder C:\Users\<username>\AppData\LocalLow\David Szymanski\Dusk
Open with notepad output_log.txt, Ctrl+F "soap", we need the latest mention
Prefix ep1, ep2, ep3 is a number of episode, binary sequence a few lines above is a levels where 1 is soap found and 0 is soap not found
This is how we find out which levels we need to replay
If there are no entries for other episodes, run through any level from the desired episode and reopen the logfile
Hope this helps someone

Shit, didn't think I could look in there. I found this on my own by using SAM and checking the epX_soap values.

One thing they don't mention is that in order to refresh it you have to grab the soap in the level you run through

I cannot find the 'soap' part of the file. Am I doing something wrong?

[Carnifex]

This helped me find one soap I missed. Thank you.

@Kugee even after going to through those files, i still cant find the 100101's that i need to find, help

I'm typing soap in the find but its saying it cannot find it, wtf? I'm pretty sure i'm doing everything correctly

Just a bit of clarification, the sequence reads N123456789(10)S , N being null.
That is to say, the first bit represents nothing, it's meaningless. Bits 2–11 are levels 1–10, and the last bit is the secret level. Hope this helps.

@Tulip what are A and B?

[Tulip]

Just to add another point here: the bits seem to be read from the left, not the right, i.e.: the sequence is: S123456789AB

So a value of 011011111111 means:

011011111111
S123456789AB

To complete:
- secret level
- episode 3
