Sorry to keep piling on, Nallor. We apparently have a problem (anything placed in an AE storage device will randomly disappear) with ApplieEnergetics and TickThreading (FTB Ultimate). One of our guys made a post on the AE MC forums and received a response from the mod author:

AlgorithmX2
This is related to TickThreading, apparently theres some issue with chunks not saving or something.

I've looked at the TT logs and can't see anything that mentions AE, although we're getting dozens of this message (which may be totally unrelated):

Got a server deadlock on build 1097. Relevant logs available here:

https://dl.dropbox.com/u/107143465/crashlogs/ForgeModLoader-client-0.log
https://dl.dropbox.com/u/107143465/crashlogs/ForgeModLoader-server-0.log
https://dl.dropbox.com/u/107143465/crashlogs/patcher.log
https://dl.dropbox.com/u/107143465/crashlogs/tickthreading.log

It went fine till I clicked join in my client, then the server did that.
Let me know if you need more info to fix the bug, or if its a bug with some other mod.
That should be fixed in 1101.

Since this mod has to do with tps, I am right in presuming this will only work for servers. Do you think turning my singleplayer world in a server will help me?

Vineet, yes it will, even without this mod. Using a server offloads some of Minecraft's work onto the server CPU/threads. This means you basically turn Minecraft into a dual core game, 1 for client, 1 for server.

Hi there.
The Direwolf pack version 5.2.0 and your latest 1106 build throws this error in the cmd.
Just as a note:
I removed Modularpower suits, xreliquiry, and Graviygun
I added Trecapitator and its dependancy
...And i hope i use spoiler correctly here,

It throws this error 17 times one after the other then stops until it tries again.
/save-all throws it as well
Im asuming its because zycraft or chicken has updated and your not caught up yet but i figured i would let you know.
If i can give you any more info that helps let me know.
Btw your mod rocks.

Build 1119 everything seems to be working good.
Quick question though,
I have read a couple of places that i can use this on my client for sp but when i try it i get this error
03-12 22:11:30 [INFO] [STDERR] java.lang.NullPointerException

03-12 22:11:30 [INFO] [STDERR] at java.lang.Thread.run(Unknown Source)
If i read wrong then no biggie my sp world is on a server anyways but figured i'd try it.
I did have optifine in but it does the same without it.

Found this mod a few days ago. Tried to use your mod after Mindcrack pack being updated to 8.2.0. All cores are being utilized nicely and TPS looks good.
However I got some logs here that is causing me trouble after the server started up.
Immediate after the server start up. I got this message in the server log

Then I shut down the server and uninstalled TT for now because it made the server unplayable.

I am not sure if I was running too fast the server cant keep up since I was wearing boots of traveler with haste 3 on it and I suppose I can go even faster with quantum pants.
But it never happened before installing TT and does not happen again after I removed TT.

Hope you can get the bugs fixed. Keep up the good work. I like this mod.

question:
i downloaded ftbserver.jar, followed instalation guide and patched it with TT build 942
then i uploaded it on dedicated server, but i had to move "ftbserver.jar" to "/jar" directory. server starts, all mods are present and seams to be running except TT
im getting this error message in the console:
Code:
[Server] SEVERE TickThreading is disabled, because your server has not been patched or the patches are out of date
(it works when i start the server on my PC without ftbserver.jar moved to any folder)
what am i missing here ? is there some config i should modify ater moving "ftbserver.jar" file ?

Since the server did not crash, I decided to log in and check around to test. I keep getting constant End of Stream disconnection.

Then I shut down the server and uninstalled TT for now because it made the server unplayable.

I am not sure if I was running too fast the server cant keep up since I was wearing boots of traveler with haste 3 on it and I suppose I can go even faster with quantum pants.
But it never happened before installing TT and does not happen again after I removed TT.

Hope you can get the bugs fixed. Keep up the good work. I like this mod.

Should have a fix for this in latest either later tonight or tomorrow.
