The developer of one of the plugins is kinda random ignoring him and it’s kinda slowing him down recreating it
I believe there were too many glitches and bugs due to the plugin never getting updated. And people stopped playing near the end. I could easily be waiting over an hour for a 3rd person to log on. Hell, if there are less than 15 people on then it's boring anyway.
tbh it was so much fun with 40+ players. if they bring it back, it would only be fun if the server is alive
I doubt it will return. https://www.planetminecraft.com/project/infection-1-12/ here's a singleplayer version
