well it turns out that you do lose 90% of your stuff even if you`re in the fed if you got your crab on the market. Sucks cuz i had 500 million food on the market and it was reduced to 50 million. That`s 150 million food I needlessly lost. =/
I am not actually sure... but it would probably be a good idea to buy your stuff back. I seem to remember glitches with stuff on the market. And you lose 2/3 of everything, 90% of your fleet, for being in a UW holders fed.
