    new horizons pack ? I think this has to be fixed by ftb

    This is a common thing, this looks to be something to do with a mod called 'CompressedStreamTools' or at least a class. This also has something to do with an NBT tag, so basically there is something that is assigning an invalid NBT tag possibly.

    I am getting the exact same error in my custom mod pack. Really annoying.

    Could just be that mod version isn't working right, I have yet to get into 1.6.4 packs so I'm not the most reliable on this topic.

    I've had this error since FTB Ultimate, presumably it is two threads trying to edit the same NBT tag simultaneously. Maybe a poorly coded mod that doesn't use locks? Not sure.

    It is a rather odd error, I find that while my server shuts down during a restart two mods seem to have issues "saving". Applied Energistics' Controller throws a save error as well as Mekanism's Universal Cables. Both which I believe are classified as entities.

    I started seeing this spam on my server after I put an Ender-thermic pump in the nether with a Ender Tank, after I removed them no more spam...I already made a post on extra utils thread but could be something else not sure at this point.

    You guys using ender-thermic pumps in your worlds? What happens if you pick those up?

    Ok so I'm having this problem too and it has caused me to have to restart my world at least twice already in the last week. I have been using the ender-thermic pumps but removing them has not stopped the constant spam in the server console. Does anybody actually know how to fix this or have we got to wait for an update of the pack. (I am using Monster 1.0.3 btw)

    I am having this issue and I am not using an enderthermic pump anywhere. I am using a regular BC pump and have setup an AE network.

    It is a general chunk loading issue, I have found its not just the enderthermic pump. Any block that chunk loads causes the problem.

    That is cool that you have found it. Is it fixed in a newer version? Maybe we should post that in his forum?

    Be my guest. If he doesn't fix it, i'll post a fixed version for you guys later tonight.

    an update would be nice because this is what seems to be slowing my server... it slows my CPU drops to like 1% and then everyone gets socket errors. Crazy this is so unstable.

    The author posted this recently on his forum "Retrogen is broken and not supposed to be in use." However, he is still registering the RetroGenController with Forge's EventBus which continues to monitor ChunkDataEvent.Load events.

    Link removed as requested by author. Contact him to fix the bug.

    Im getting spammed by this in console and the only answer we get from Reika is, "The class itself is in DragonAPI, but the execution is called from the mods' end. DragonAPI does very little on its own.
    In all likelihood, it is not the retrogen doing this."

    If you could post a fix, would be very appreciated.

    update to the newest version, 15b. He disabled his retrogencontroller and I am no longer getting the console spam on my server.

    blood I would like to thank you for finding the offending mod, I spent so long searching an answer. Much appreciated!
