Expansion mod

It could be the DL. Github can sometimes time-out before DL'ing the entire file, and as it doesn't show you how big the file should be you don't know if you've got the whole thing or not.

Zip fill fail on unpacking in this case

Ah i was wondering the same thing, when i downloaded that mod and wasnt sure if i miss something. Didnt show anything after switching theme. Oh well i try again, need to redownload the game and the mod lol.

Oh well didnt work either, guess i am missing something like additional files to add. Otherwise something isnt right here.

Try this steps:
1)Remove any mods from game, restore game to original files via steam or whatever platform.
2)Launch game, start new custom empire game and check that there is no error with ship build window.
3)Install one of problematic mods, switch theme to mod, exit game. Start new custom empire game and check that there is no error with ship build window.
4)Switch back to original theme, exit game. Install EM mod. Start new custom empire game and check that there is no error with ship build window.
5)Switch to mod theme, exit game, check for errors.

This should narrow down where problem occurs. Also you can try newer alpha versions, they don't have any fixes for this bug, but will remove possibility of corrupted files.
