[0.13.15] Missing Mods/Folder

[PiggyWhiskey]

I'm converting my ZIP installation using --mod-directory to steam using Shortcuts. (ISP download issue, 3 hour download times for updates)
I've changed config-path.cfg to "__PATH__executable__/../../config"

Attempting to Launch
"E:\Program Files\Steam\steamapps\common\factorio\bin\x64\factorio.exe" --mod-directory "..\..\fmm\Vanilla_Factorissimo"

Vanilla_Factorissimo contents

autofill_1.4.1.zip
blueprint-string_3.1.1.zip
clock_0.13.0.zip
EvoGUI_0.4.106.zip
factorio-reach_2.0.3.zip

steinios_research_sensor_0.0.2.zip
WaiTex_Full_1.1.0.zip
Warehousing_0.0.10.zip
YARM_0.7.102.zip

However the game doesn't load with those mods at all.
Did some random testing installing "20x20Slots on Power Armor MK2"

Factorio Mods UI

And I can't find the actual location of that mod. A windows search can't find it in the Steam Folder, E:\Program Files\Factorio (my ZIP standalone folder) or APPDATA\Factorio.

Is there any way to find what folder Factorio is using to save/download this mod?

Running the game without --mod-directory works as expected with no mods loaded,

Config/Saves works as expected.

Can you post the log?

After some tracking and searching of the entire drive (E:) and found the folder.
E:\Program Files\Steam\steamapps\fmm
instead of the intended
E:\Program Files\Steam\steamapps\common\Factorio\fmm\Vanilla_Factorissimo

It looks like Steam or Factorio isn't using the correct target location to allow use of "..\"

It looks like Steam or Factorio isn't using the correct target location to allow use of "..\"

It looks like Steam is launching Factorio from E:\Program Files\Steam\steamapps\common\Factorio\, which sounds completely reasonable to me.

Not a bug.
