Done server crashing when certain player enters (assuming)

VastCreatorHD
(it's done it atleast 3 times each time he/she has joined)

could someone see what's on his end and see if it can be fixed so it doesn't?

 

Oh, sorry guys. Whenever I join the server, I always crash before I load. Didn't know it crashed the server itself.
I've disabled optifine, fastcraft 1.21, and even hard force updated the pack. Nothing works.
Any help?

 

Would you be able to upload a crash-report for us?

 

@Administrator Looks like this may need a log search around the times as I didn't see any crash-report (unless they weren't uploading). Please work with the player to fix.

Looking into this. Looks like EC3 isn't playing nice with extra utils.[DOUBLEPOST=1436707462,1436706207][/DOUBLEPOST]Ok - patch applied. Heading in game to test now.[DOUBLEPOST=1436708841][/DOUBLEPOST]Alright - this is no longer a server-side crash. I'll kill that transfer node so you can log in vast [DOUBLEPOST=1436709742][/DOUBLEPOST]Issue is resolved vast. Please don't re-create this configuration again, as there's not much we can do about the client side crashing

 

Thank you
