Design flaw or error?

[Rich.h (OP)]

I seem to be getting an error with a design, although I feel it could well be a jump drive issue. Each time I add a jump drive to this design I get a window with this.

"error in round
error 6 generated by aurora
overflow"

This happens whenever I add the drive in the design screen, or if I select the design later in the design screen, or anytime I try to highlight any ship of this design, such as the individual ship window. Here is the ship design.

The jump drive in question here is size 1680 HS, I also tried to use a 960 HS and a 778 HS drive and get the same error. I was able however to add a 389 HS drive with no error (although this is a drive too small to allow this ship to jump), as well as a 1800 HS commercial only drive. I know there is a limit with jump drives but was under the impression that ships of up to 1.2m tons could be made to be jump capable, so is this a bug or have I just made an error with my design?

[Rich.h (OP)]

Just to add that this error is also being applied to any ship that becomes a parasite of these designs. Even after a ship is launched from the hanger, if it is then selected in the individual ships screen this error is added to them.

Correction. Actually it is being applied to any ship that joins a TG with this design in it.

I've been throwing a similar error, but in cboGame, whenever I either generate a new system or select my game in the game details screen. I've been exploring exclusively via jumpgates, though.

One thing really stands out to me on that design. The Hyperdrive.

I'm fairly certain that hyperdrives aren't functional and that could quite possibly be what's causing these errors. I'm also wondering how you got access to them as I've not seen anyone else on the forums talking about them...

He named it hyperdrive for fluff, but it's only a jump drive.

Since your ships are so much bigger than anything I usually play with, I would assume you are overflowing one of the myriad of variables assigned associated fleet.  Steve might be able to tell you which one at a glance, or if he has the time you might email him the database and he can find the problem, but either way the only solution might be to have less of whatever it is that is being rounded.

If you notice with this design though I actually do not have that many copies of the same item (other than engines). In addition the problem only happens when I add a jump drive, I can happily double everything on this design with leaving the jump drive out and no error. Also this error occurs everywhere this design or ships of this design is selected, so the design screen and the individual ships screen. Even if I put a single ship in a TG I still get errors happen, clearly there is a rounding problem here but I am just wondering if it is caused by jump drives while still working, not actually liking ships of this sort of size.

[Vandermeer]

I would bet that the problem here comes from the 0 maintenance life, which is always likely to cause rounding errors. If not that then it could be from adding maintenance storage bays, because these I know to bug out on reasonable size with the same error.

I would propose to add more engineering and see if the problem disappears, but otherwise I have no idea. (I tested military jump drives on ships up to 600kt btw. without problem, and in current version.)

Well that seems to have fixed things, a quick addition of two engineering spaces and the error vanished. I am still getting a zero maint life but I guess somewhere it is registering it as a tiny amount that simple gets rounded down. I do find it odd though that this is being caused by that in a game where I have overhauls and maint life turned off.
