Using IE 0.12-78 with Forge 2618

One of our players started automating pams harvestcraft and is using hoppers and item routers. I don't exactly know what he is trying to transfer, but our server crashes on startup with the following: https://hastebin.com/amiwixiran.pl

Any help would be greatly appreciated, the guys are going mental without their daily MC fix (and are letting me know every hour!) :-P

Cheers <3

So I'm guessing this means it has nothing to do with IE then?

Any recommendations what to do best now? Mcedit to get rid of the hopper?

Cheers

No, that means it is an IE bug that is fixed for the next release ("closed this in <...>" vs just "closed this"). MCEditting out the hopper or the routers is probably the easiest solution. There are probably 4 routers in a square (with some very specific settings), those are the ones causing the crash.

Oops didn't see the commit :-)

Cheers, keep up the great work!
