One of my friends once randomly got kicked from the server after being on there for nearly an hour and now this keeps on poping up in the console when he tries to join, other players can still join without issues, and no act is not the name of a mod and he's using the right version of the modpack.
[16:13:19] [Netty IO #0/INFO] [FML]: Attempting connection with missing mods [act] at CLIENT
And sometimes it gets followed by a spam of this error:
[16:18:43] [Netty IO #10/INFO] [FML]: Unexpected packet during modded negotiation - assuming vanilla or keepalives : net.minecraft.network.play.client.C00PacketKeepAlive
