Server Crashing randomly (java.lang.String)

[Glaskuchen]

Hey Guys, my Server crashed randomly when my friend clicked on the wandering Traider. Similar Cras happend when he placed multiple Backpacks next to each other. I think its the End Remastered Mod but i could never just remove it cuz of the Progress we've made there. Can someone help me i would be very thankful. Thats the Crash Log:

Problem with End Remastered. Make sure you are using the latest version.
If the Mod is already up to date, report this bug to the Mod author.
