20240304 1170.0.0.0 regression - the lwi file is always recreated instead of using the cache

[FranceBB]

Starting with version 20240304 1170.0.0.0 there's a regression about using the lwi files.
The version before the latest release was checking whether there was an lwi file in the same directory as the file and if it was written with the same version of LWLibav.
If it was written with an older version, then it would recreate the lwi index, otherwise it would use the one it found.
In this new version, however, it recreates the lwi file every single time, not just with AVSPmod mod but also with ffmpeg and any other application.
For instance, in this very same unchanged script, we have two different command lines calling ffmpeg and it's recreating the index files both times:

video=LWLibavVideoSource("V:\fs0\clip.dir\HSM00342.mxf", cache=true)
ch12=LWLibavAudioSource("V:\fs0\clip.dir\HSM00342.mxf", stream_index=1, cache=true)
ch34=LWLibavAudioSource("V:\fs0\clip.dir\HSM00342.mxf", stream_index=2, cache=true)
ch56=LWLibavAudioSource("V:\fs0\clip.dir\HSM00342.mxf", stream_index=3, cache=true)
ch78=LWLibavAudioSource("V:\fs0\clip.dir\HSM00342.mxf", stream_index=4, cache=true)
audio=MergeChannels(ch12, ch34, ch56, ch78)
AudioDub(video, audio)

Setting cache=true doesn't affect it as it keeps recreating it anyway and it's set to true by default anyway even when it's left unspecified.
I tried with cachefile but it is still recreating it:

video=LWLibavVideoSource("V:\fs0\clip.dir\HSM00342.mxf", cache=true, cachefile="V:\fs0\clip.dir\HSM00342.mxf.lwi")
ch12=LWLibavAudioSource("V:\fs0\clip.dir\HSM00342.mxf", stream_index=1, cache=true, cachefile="V:\fs0\clip.dir\HSM00342.mxf.lwi")
ch34=LWLibavAudioSource("V:\fs0\clip.dir\HSM00342.mxf", stream_index=2, cache=true, cachefile="V:\fs0\clip.dir\HSM00342.mxf.lwi")
ch56=LWLibavAudioSource("V:\fs0\clip.dir\HSM00342.mxf", stream_index=3, cache=true, cachefile="V:\fs0\clip.dir\HSM00342.mxf.lwi")
ch78=LWLibavAudioSource("V:\fs0\clip.dir\HSM00342.mxf", stream_index=4, cache=true, cachefile="V:\fs0\clip.dir\HSM00342.mxf.lwi")
audio=MergeChannels(ch12, ch34, ch56, ch78)
AudioDub(video, audio)

Even changing the disk didn't change a thing:

video=LWLibavVideoSource("A:\Ingest\MEDIA\temp\HSM00342.mxf", cache=true, cachefile="A:\Ingest\MEDIA\temp\HSM00342.mxf.lwi")
ch12=LWLibavAudioSource("A:\Ingest\MEDIA\temp\HSM00342.mxf", stream_index=1, cache=true, cachefile="A:\Ingest\MEDIA\temp\HSM00342.mxf.lwi")
ch34=LWLibavAudioSource("A:\Ingest\MEDIA\temp\HSM00342.mxf", stream_index=2, cache=true, cachefile="A:\Ingest\MEDIA\temp\HSM00342.mxf.lwi")
ch56=LWLibavAudioSource("A:\Ingest\MEDIA\temp\HSM00342.mxf", stream_index=3, cache=true, cachefile="A:\Ingest\MEDIA\temp\HSM00342.mxf.lwi")
ch78=LWLibavAudioSource("A:\Ingest\MEDIA\temp\HSM00342.mxf", stream_index=4, cache=true, cachefile="A:\Ingest\MEDIA\temp\HSM00342.mxf.lwi")
audio=MergeChannels(ch12, ch34, ch56, ch78)
AudioDub(video, audio)

adding a simple:

tweak(sat=1.31, dither=true)

as an example, makes it recreate the .lwi

I am unable to test right now but can you confirm the issue does NOT occur with 20240112 1167.0.0.0 as I would like to rule that out.
Thanks
