Cyclic interaction detected between ccbgssse002-exoticarrows.esl and ccbgssse002-exoticarrows.esl

I'm running loot on linux, through wine. Same issue occurs with all CC esls. Loot debug log: https://drive.google.com/file/d/1QauUiNgyiOQ-g6uXDCEvXQUffTL8Lx4T/view?usp=drivesdk

Repeating what I said on Discord for future reference, I thought this is probably due to me misunderstanding what std::filesystem::canonical() does on a case-insensitive filesystem, I think I expected it to return the true case of a given path (since the path must exist for the function to return).

However, it turns out I actually wrote a test for this, and that is the behaviour on Windows (possibly only on NTFS): but it doesn't seem to be the case when running through Wine on Linux on some unknown filesystem, and any of them might be responsible for the difference. I need to do more investigation.

@monyarm What kind of filesystem do you have Skyrim SE installed on, and are you running it with any unusual config (e.g. case insensitivity), so I can try replicating it?

[monyarm]

I'm running it on ext4 with casefold (aka case insensitivity). I can also get you my exact kernel and wine/proton versions if you need them.

Another thing I've done that is unusual, is that rather than logging in and downloading the CC content from withing the game, I instead just copied the bsas and plugins from my other pc. (I'm on rural internet).

Kernel is 5.11 tkg-linux, with all the default patches, plus the futex2 patch, compiled with 03 and mtune and march. Wine/Proton Version is proton_tkg_6.2.r0.g3b5ea332, with the following non-standard config settings:

_mtga_fix="true"
_community_patches="amdags-proton.mypatch origin_downloads_e4ca5dbe_revert.mypatch ID3DXEffectCompiler-partial-implementation.mypatch ntdll_Map_top-down_if_dll_characteristics_include_DYNAMIC_BASE.mypatch fsync_futex2.mypatch wine-fix-gcc10.mypatch Shell32-CreateDirectoryInDestinationInFileOp-Move-multiop.mypatch"

Actually, wait, that's my global wine/proton version, but I just remembered that I'm using a different version for Vortex itself (and all software run through it, like loot), that being Wine 5.21-lutris. Which is a more standard wine version.

I'm able to replicate this in an Ubuntu VM and Wine 6.0 after mounting an ext4 filesystem with casefold enabled and setting up a dummy Skyrim SE game in a directory that has case folding enabled. I think the problem is that std::filesystem::canonical() is modelled after POSIX's realpath, which doesn't output the path's "true" case when case folding is in use.

I've replaced the usage of canonical(), @monyarm can you try replacing the libloot DLL in your LOOT install with this libloot DLL?

[monyarm]

It worked, now i can finally mod my game again.

OK, closing this as it's fixed by 505106d602caf0c2825d613f7bc7b1f9aad7527f.
