I'm aware it's mistake and such, there is no arguing about it, problem is, that game is quite unclear with Error and doesn't want to load.
You get only dialog stating "bad conversion", and that is all.
also logfile is rather "unclear" about cause of error
i would expect at least error, while parsing mod or something "more informative", i just spent over 10 minutes searching for cause of issue, since i was playing quite happilly yesterday, and there was not update (neither to game or mods)
log
STR:1) drop random zip file into mods directory
2) launch game
btw. if i place same file into "saves" i get following error when clicking load
File C:/Users/Josef Micka/AppData/Roaming/Factorio/saves/CommunicationLog.zip/info.json not found
quite obvious where is the problem
