Post-processing chain is case-sensitive

As it says on the tin. I have one particular shaders directory, EpochReshade, which looks like so:

When the engine tries to load this directory it dies with this error:

[14:09:08.113 I] Saved input bindings: /home/sk3shun-8/openmw/umomwd/starwind-modded/input_v3.xml
[14:09:08.113 E] Unexpected destruction of LuaWorker; likely there is an unhandled exception in the main thread.
[14:09:08.211 E] Fatal error: filesystem error: cannot get file time: No such file or directory []

Removing the relevant data= entry resolves the crash, but there's no obvious indication as to why it would be crashing. Other postprocessing packs I have installed work fine, and are even adjacent to the offending EpochReshade directory. I thought perhaps there might be a case-sensitivity issue hiding in here, but no.

This is the startup command I'm using: openmw --replace=config --config "$(pwd)" --user-data "$(pwd)" --data-local "$(pwd)"/data/ Which does indeed have the data directory and all the usual suspects one would expect for the user-data directory.

If a fix is forthcoming I think it should probably go to .49 as I strongly doubt users are gonna be able to debug this effectively, and also this really really really seems like it should never have happened in the first place. I think it may be a regression from something, possibly some of the VFS work elsid did? but I know this setup was fine before when I put it together originally, somewhere during september.
