With no announcement, the workshop seems to be working again. There shouldn't be any issues downloading or syncing mod files, world is back up where it was.

Happy Thanksgiving, don't eat anyone I wouldn't eat.

So, according to the SpaceEngineers Discussions forum, the recent issues with downloading mods from the server have to do with recent Workshop maintainence.

Until the issues are resolved, I'm spinning up a vanilla creative world, same address. I'll post an announcement/event as soon as ♥♥♥♥'s back to normal.
