"Hello,I am experiencing a server crash whenever my contraptions (Create) interact with the world while playing with the Sable and Aeronautics mods installed.Crash Log:
I have attached the full crash report: crash-2026-06-20_22.57.07-server.txt. Issue Description:
The server crashes during the tick loop with a NullPointerException. The stack trace points to a conflict within com.simibubi.create.content.contraptions.ContraptionCollider. It seems that both the Sable mixin and the Aeronautics mixin are attempting to modify this class simultaneously, leading to a failure to read mf.axis. Error line:
java.lang.NullPointerException: Cannot read field "x" because "mf.axis" is null. Environment:Minecraft Version: 1.21.1Create Version: 6.0.10Sable Version: 2.0.3Aeronautics Version: 1.3.0I've checked the mod list and both Sable and Aeronautics are present. Please let me know if you need any additional information."
