I updated the mod just now and it stopped working. It is present in the mods folder, but it does not load, and I see no error message.
factorio-current.log has this message in it after downloading the mod:
29.585 Error CachedChangelog.cpp:54: Failed to parse changelog for mod Alien Biomes: invalid changelog file, error on line 1, line does not start with exactly ' - ' or exactly ' '..
It also has this line that appears during startup:
0.339 Error ModManager.cpp:793: Mod package read error. Opening zip C:/Users/Dirk/AppData/Roaming/Factorio/mods/alien-biomes_0.4.11.zip failed: Bad zip file
Despite this, I can open the zip file in 7zip and read everything just fine.
Edit: testing the zip file using 7zip reveals a data error at graphics/terrain/sr/mineral-aubergine-sand-2.png
