Don’t know if this bug is reported earlier, but i 1st noticed it sometime ago in 1.0X version and was hoping it would be fixed already.
1) Design a new ship, using the ship name from the earlier games. ( overwrite old design when game asks for it )
2) After this i can't build these new ships using 'build ship' button in the main screen. Game just won’t let me select it. I have to 1st open the colony management screen and from there select to build that new ship.
3) And now things get even more interesting... everything shows that i am building the ship that i just designed, but when it is actually build, i don’t get the ship i wanted, but i get the ship from my earlier game (ship you that is supposed to be overwritten when game asked it as i saved my new design).
With this bug i can build any kind of ship (that i have designed in my earlier games) in any stage of the game, just by the cost of the empty tiny hull.
I hope that this is fixed in 1.1 as it’s very easy to use this bug as an exploit, by accident or on purpose, and it’s also very annoying.
