Yogbox! Combining too many mods to count!
Ew....
Yogbox is crap. Some of the mods may be good on their own, but when you mix that many together you get a heap of redundant and duplicated functionality, as well as a ton of game balance issues, and a heap of useless add ons that do nothing but detract from gameplay because there's so many from each mod you can't keep track. Not to mention the amount of pain mod packs give mod authors, when a bunch of yogaboos come into their forum threads and complain that their mod doesn't work: "Y U NO MAEK UR MOD COMPATIBLE WITH YOGBOX AND ITS THOUSANDS OF BASE CLASS EDITS HURDUR"
It's like if you went and installed Better Than Wolves, Buildcraft, and Industrial Craft all at the same time. BTW would become completely useless, because theres nothing it can do that BC and IC can't do better. But if you play BTW on it's own it's an epic mod, it's not as powerful as BC and IC sure, but it fits the vanilla gameplay so much better, and has a proper tech tree that you have to navigate through with hard work...no easy skipping right to the most powerful stuff at the end.
If you really want that many mods, it's better to make several copies of your minecraft installation with a selection of mods on each. That way you don't get a lot of redundant mods conflicting with each other, and when you want a different play style you switch to your other minecraft installation.
So, found the cause of the server troubles. Just got a message from the provider:
Hello,
If you're getting this message, that means your IP address is currently victim of a Denial of Service attack, also know as DDoS/DoS attack. Our service provider is currently working on mitigating the attack right now so in the meantime your server will not be accessible until they have fixed the issue for us. If you have any questions or concerns, please let us know and we will be happy to assist.
WELP.
o.o who would wanna devote all those resources to shutting down a small minecraft server that has like max 3 players on at a time?
Or is there something else important at your IP?
