The reason is CurseForges' Launcher is missing the default Minecraft JAVA Arguments, without these will cause client lag such as judders or client lockups, commonly known as lag spikes. To fix CurseForge Modern City Modpack lag, do this:
- Open the CurseForge app
- Click Cog > Minecraft
- Add this to Additional Arguments
- Increase the Allocated Memory to modpack authors recommended settings
- Click the top-right
- Restart the Modern City Modpack, for no lag
Everyone who plays on your server will need to do this, share this page with your community.
Using this script you can manually reset your Modern City Modpack map and start over with the pack on a fresh new world
Run the script by opening your Multicraft panel and clicking on “Console” on the left-hand side. You can then enter the command into the text box and hit “enter” or “send” to execute it.
With the “-d|-b” being a choice of one option and WATERTON being the name of your new map type.
The two options of “-d” and “-b” will decide what happens to your existing world.
“-d” will delete the world and not keep a back-up of it.
“-b” will create a back-up of your existing world and save it as a .zip folder on your server.
