UPDATE 15/2/22: Cities Skylines developer Paradox has issued a statement on the weekend’s warnings surrounding several mods.
The blog, posted via Steam, details the issues it has found with the dodgy mods in question, and thanks fans for being alert to potential issues. In short, the situation is not perhaps as dire as it was feared.
“We recently banned a few mods from the Cities: Skylines Workshop and want to clear up some of the misinformation surrounding these mods,” Paradox wrote. “The mods in question, which have been banned, are ‘Network Extensions 3’ and ‘Update from Github’.
“No keyloggers, viruses, bitcoin mining software, or similar has been found in mods on the Steam Workshop.
“‘Network Extensions 3’, the mod alleged to contain malware, was banned due to discriminating against specific Steam users. First, it blocked a short list of Steam users from using the mod, but this was later changed to cause what appeared to be buggy gameplay. Blocking users or creating specific restrictions for them violates the Steam Subscriber Agreement and such resulted in the mod being banned.
