u/FragmentedMine

So I started a lightly modded real for me and friends, the closest server host is Illinois, I have about 15 mods (most are small stuff like health bars, lighting, etc). We are building a bit close to each other with no huge Redstone machines if any at all, no large amounts of mobs and only a highest count of about 6~7 people playing at once but at times theres the classic block place delay or we have this levitation spell from a mod that when we try to use it rubberbands us really bad. I'd like some way to fix or diagnose what may be the issue contributing to this in a move to fix it.
