[Emperor's Child]

I've recently played as a non-pirate (to check out some of the different tech combos), and began to build some of the large hulls but found a funny problem I'm hoping somebody can help with. (I've tried to search for this, but either came up with so many hits I'd be reading for a week or came up with nothing...)

With both the base-ship and battle-moon I find that as I add additional engines the maximum movement at some point reverts back to zero. With the basemoon, it fluctuates from zero to one and then back to zero. With the Baseship, I can raise the movement to eight and then it drops back to zero and begins to increase again as I add more engines.

I think that this is a code / data structure issue since it looks to me like there is some type of database out of bounds issue with the numbers going on that has the effect of zeroing the movement once some value raises over a certain amount. Without the source code it is hard to say, but I found that by playing with the base moon number of engines required to move I could increase the movement achieved before the values dropped back to zero, but they always seemed to drop back at some pre-determined point.

Has anybody seen this go on with their P&N games?
