server crash on world unloading

[Azurl]

Hi! I get server crashes when I use chunk loaders in the nether and my workshop if I'm in a different age, I'm running the latest DW20 pack. the server successfully (I presume) Unloads world 1. 15 seconds later the server crashes, ArrayList out of bounds exception.

anyone else getting this?

I'll upload the crash report so anyone with knowledge might find something.

Are you perhaps using a lot of redpower timers? The last time i saw this error was because i had an assboat of timers on a 0.025s rotation, and all those ticking updates tended to overload people. If yes, slow them down to 0.5 or so, and you'll get the same effectiveness with less effort.

Nope, haven't started using redpower very much yet, mostly thaumcraft. I have a lava pumping station in the nether that I kept chunkloaded in the FTBBetaA pack. since the update to DW20 and 1.4.6, the world anchors require fuel, and as I put fuel into them, the server started crashing when unloading nether ( I presume that is what it wants to do at least since it unloads world 1 before it crashes.

its a fix for something that sounds just like your problem.

Is it safe to apply this fix in the modded jar from FTB?

I don't see why not, but backing up your mystcraft jar and your world files are never bad ideas.
