Someones Clean up Brit house. Just stockpiling items waiting for it to be released. It's basically a system where you put items in a special trash barrel and get special coins for it. http://www.uorenaissance.com/info/CleanUpBrit
So clean up britania is suppose to help make less items in the world, but people save more items that they would otherwise just trash.. and then after this one they will continue to save more items that otherwise would just be trashed.. Sounds kinda counter productive unless im missing something
Unless I'm mistaken, I believe the UOR CUB system is supposed to be an ongoing thing. Not like a one-time event. I may be wrong though.
I've seen the effects of CuB on several shards, an item chart on a previous shard showed that there was a massive spike in item count during the CuB period. My memory is a little foggy, but during the CuB period, enough items were added that it basically simulated 3~ months worth of regular item accumulation.
