Summary0002843: "copy game setup to lobby" not as useful as I had hoped
DescriptionSeveral months ago I had a game where the AI started with a certain kinds of bonus ships (including my bane of 4.0: Electric Bombers).

I was hoping to remake that scenario but when I loaded it up the starting ships were different (no surprise since it now gives more starting planet options)

It also failed to change the map type and planet count options, it just made the map the way it was regardless.

Further attempts to recreate the game (after fiddling with a few other things) failed to even remake the map.

The random number generator has been tweaked quite a bit since 4.0 (mostly to fix some "random number generator not being random" type bugs). Although this did helpfully fix many odd issues with randomized behavior (like resolving unit collision), it had the sad impact of changing how seeds map to bonus ships and galaxy layout. In other words, a seed that gave one layout of the galaxy and bonus ships in 4.0 could give a very different layout and bonus ships in 5.0 (even taking into account which expansions are enabled, which does effect the bonus ship availability)

I had already commented on how brittle relying on a random number generators seed for persistence of layout options is (and I was proven right), and I had made a suggestion (0002200) to separate the seed from the layout to help make changes to the RNG less fiddly with maps and stuff, but it is apparently not a big priority. (Which I understand, changes to the RNG should be VERY rare after all)

That solidifies my situation even more, though that makes current tries unreported (thus far)

Sorry to hear that, but short of copying over galaxy layout data from your old save into your new save (not recommended, as I have no idea what the save game layout is like), or the VERY small chance you encounter a seed that gives similar results to the map you had before, your "quest" is somewhat hopeless.

Let's hope they don't make any changes to the RNG anytime soon.
