I created a lan server and my freind came on. We had HEE downloaded and we spawned the new bosses. When we spawned them, my friend got disconnected from the server. He did not crash. I treid killing all the bosses by myself. When they were gone, my freind was able to join the server once again.

Could your friend provide logs? I'm not able to test LAN.

my friend did not crash, he disconnected meaning there was no crash report to post for the bug report. Disconnections will take you off the server and bring you back to the home page. disconnecting does not provide crash logs.

Not crash logs, I need the client logs.

Disconnecting did not provide me with any client logs. That unless I had deleted them when I was refreshing the minecraft crash report folders.

You always have client logs saved in .minecraft or .minecraft/logs.

my friend had the disconnection so he might have the client log instead and what I mean by refreshing is I deleted everything in my .minecraft folder

No log, no help.
