So recently two buddies and I started renting a server so we could play on a custom modpack of ours. When we play alone on the server, every aspect works to a tee. When there are two or all three of us on, most of the time we crash after teleporting (We use essentials, so /home, /back etc.) and other times all three of us crash randomly at any given time. Sometimes myself alone will join the server and literally turn around, only to crash.
Here's the list of mods the server and us client-side are using:

Make sure Optifine is up to date and the version is matching your Minecraft and Forge version.
I'm the only one of the 3 of us that is using Optifine, it is the same version, and crashes persist.
