Hello
I suppose the title says it all really. The maximum deficit that you can go into is -2000 and so if you upgrade your entire fleet of ships in one go it would plunge you into debt no more than that after one turn. I have read a post that suggests that this was a design feature and not an exploit bug which will be fixed. Up to now I have avoided using that, even though I'm really struggling, as I have been met by fleet after fleet of enemy ships with very strong combined beams and mine have quite low shields, unless protected by a starbase.
So is this a recognised feature of the game ,that has been allowed for, or is it just an exploitable bug to be fixed in some later patch...?
