So I thought I knew how all of that worked, but now I'm more confused then ever. It says clearly in the game, if an item needs more credits than the monthly production can give, it'll require more months, makes sense. And as long as you have money coming in (meaning you don't go in the negatives since each month it deducts the production cost of your current capacity) you get your shiny new ship. Correct me if I said anything wrong.
Now for an example with actual numbers. I tried building a Niagara in my playthrough (it costs 325 000 credits) and my monthly production capacity is 150 000 credits. Everyone with a pair of eyes and a functional brain can see that this would take 3 months. NOPE. I've now spent 10 bloody months waiting for this cursed piece of metal. Only one single month I dropped to 1 credit, any other month is was deducting 150k credits as it should. And when I get that intel report saying what the production cost was, I click on it to see the details and it says something like ''a total of x credits has been invested into the current production order''. I saw that number jump up and down like crazy, it went to 279k credits, meaning it should be almost complete, but next month it said 42k credits, and then a completely different number somewhere in between, it's crazy. I've been losing out on my colony income for a whole year while the ship is still in this production queue.
Either:
A) I'm an idiot and missed something crucial
B) There a possible bug causing this loop
C) The information the game gives me is just weird and doesn't make sense (on that note why don't we see the progress on the custom production tab? it seems to me like a logical place to show it instead of digging through intel)
