Describe the bug Summoning the Icon of Sin in the server is just fine when you're alone and stay near it, but when another player is present and they move out of a certain block range (30-50 blocks, unsure of exacts) of the boss, the server will have ticklag of 7000 ms per tick, possibly even provoking the tick watchdog. When all players are within this distance, however, the boss does not cause server-wide TPS lag.

To Reproduce Steps to reproduce the behavior:

1. Get 1 other player on the server to join you
2. Summon the Icon of Sin
3. Have the other player and/or you run to a position further away
4. Icon of Sin should stop moving, tickskips begin
5. If done for long enough, this could set off the tickrate watchdog and end with a forced crash.

Screenshots No screenshots or logs provide any valuable information. All we can provide is a video of this in action, server logging only reports a tickrate issue & number of ticks skipped (Worst case scenario, if the watchdog was dispatched, it'll create a "tick took too long" crash report), and client logs say nothing unless if the server closes from the tick watchdog.
