Hi.

My server crashes when I enter the shower after turning on the water:

Description: Ticking block entity

cfm-4.1.2-mc1.10.2.jar

When I restart the server, the showerhead has disappeared

Confirmed, but my friend had to remove the showerhead manually so I could login

Seeing the same thing - mount a shower head anywhere, turn it on, walk under it and server crashes. Can start server again, but server crashes as soon as player logs on in that spot.

Running on CentOS Linux release 7.3.1611 (Core).
minecraft 1.11.2
cfm-4.1.2-mc1.11.2.jar
forge-1.11.2-13.20.0.2228

Had no trouble with server until this point. Was also running with JourneyMap and Stellar mods installed, but problem continues to happen after removal of all other mods.

This occurred on our server as well. Another player was locked out of the server because he stood under the shower head and turned it on. Every time he tried to login the server crashed. I was able to successfully travel to his home and enter the room where the shower was running. After right clicking the shower head to turn it off he was able to log in again. The shower head has been removed and blacklisted as an item on our server for the time being.

We observed the same issue.

Workaround:

Adjust playerdata/*.dat file position with NBTExplorer (used wine on Linux).

Possible Fix:

I think this is the same issue as described here:

• shadowfacts/UnderwaterUtilities#7
• shadowfacts/UnderwaterUtilities#11

which is fixed here:

• shadowfacts/UnderwaterUtilities/commit/3122b187a4

Thus the problem is (referring to the commit) that client side API is used on a server.

Having the same issue here, can get around it by getting rid of the shower but wouldn't mind having it working!

Can confirm, 4.1.2 has this as well, just crashed my minecraft 1.11.2 Ubuntu Server

Will look into the issue. Thanks for reporting

Thanks for the report. Issues fixed in:
6adca00

Thanks! I'm new to this - how do we make use of the fix, or has it already been included in the 4.1.2 build?

I will be pushing a release soon!
