I see, that's not the mod's fault, you prbly forgot to replace your old archive.rpa file with the new one when you updated your game. Do that and it should work.
Uhm, you have to find to the folder where you moved the archive.rpa file into when you installed Eternum, which is the same folder you also moved my mod file into.:"Documents/Ixalon/com.caribdis.eternum/game" And then you just move the new archive.rpa file, which was included in the most recent game download, into it. Your phone might ask you to confirm the overwrite and that's it.
