i seem to have found what i think is a bug, im bleeding 12bc per turn and the numbers the overview for money says that im gaining 4bc and i double checked the numbers it gave on my PC caculator and sure enough i should be gaining 4bc not loosing 12....im not using over the max command points so i can rule that thing out and a third of my planets are on bc production so thats not it either.

yes i tried advancing several turns and i got the same thing, 12bc loss per turn regardless of the numbers adding up to more than im actually loosing. i started another game and noticed it happening again with the same problem and then on the next turn my bc income shot up to +49 even though i only had seven planets across four systems and all but two from that game were freshly settled...truth be told i started several new games to test this out and now it seems to be actually be "rubber banding" all over the place either several turns into a fresh game where im building nothing at all because i like to go with the pre-warp setting and can't build anything that would put me straight into deficit or even in a game thats up to 250 turns in with all but a select few of my planets churning out bc's for me. if the game has a problem not updating the income overview properly or even incorrectly then that is a big problem!

Can you maybe post your save game or a screenshot of the Empire Budget tooltip ?
