Expectations: assembly saved succeessfully even if it has obfuscated names/etc
sometimes it's usefull to have full sources that is easy to explore/search/etc
file names does not matter...

Note: I believe the issue is inside the following routine:

static string CleanUpName(string text, bool separateAtDots, bool treatAsFileName)

Thank you very much!

[greenozon]

@siegfriedpammer sorry bothering, I"ve taked latest CI build and still see the issue (or maybe this is diff one? but sounds very similar..)

on the attached assembly:

[siegfriedpammer]

Should work now... apparently I cancelled the decompiler too fast, sorry

[greenozon]

Thank you so much!
quick quistion: some tests failed in your PR jobs:

any ideas if thats smth should be taked care of?

[siegfriedpammer]

Yes, I messed up again... pushing too fast :(

[greenozon]

works like a charm now!
Decompilation complete in 372.3 seconds.

well, if you still have power and desire, last (I hope) issue related to this -
some exported sources do not have .cs ending for some reason I"ve checked, all are cs code):

[greenozon]

Hurrey! now we are super sorted out! many thanks!! (You also fixed issue with resources missing .resx!)
