[john-peterson]

the file structure is correct but the data block is corrupted

I will add more debugging output to that portion of the test

[john-peterson]

Can you reproduce it in Mac?

[john-peterson]

I tried to test other compression schemes by using other files but it failed

cabal run freearc -- create a README.md

I also found a bug in my build with plain text files

This is surprising since I did not change anything

Did he fix it before he created the build?

Is it specific to the build targets? My unarc.exe use the exact same headers right?

This is the beta release build

Huh, curious. It definitely did work earlier, so something must've gotten screwed up at some other point.
