Also mod update browser ingame is now completely broken :-(
Failed to parse the mod portal API response: Mod long_range_delivery_drones_peterwolf_fork dependency Battleship >= 0.1.0 not matching pattern "[?|(?)!|-] ModName [ModVersion specifier]".
Oh, yes. Same problem. I've already verified the game files and tried everything I could think of, but nothing worked. Then I checked the log and noticed the game was getting stuck on this specific mod.
hmmm ....
Factorio appears to parse the full release history, so that stale 2.1.4 record breaks the portal response even though 2.1.5 and 2.1.6 are clean....
