I did allot of testing here, not sure exactly whats going on because i wasn't able to reproduce one circumstance.

First, after placing then removing cargo containers from my galleon T, my weight jumped up by more than 30k. Then down again randomly when i replaced a sail. (not weight sails, i was running all speed)

Second, my friend and i both built galleon Ts, same server, same grid, just different times, same shipyard might i add.

His galleon, has 84k base weight, mine has 60k, the other 4 we BOTH built after the fact have 60k. What is up with this?? Its really frustrating.
