[0.12.0] Science research is lossy

We are aware of them, but they have low priority. We have more important things to do. They go here in order not to take space in the main bug thread list.

[0.12.0] Science research is lossy

Post by kosievdmerwe »

I researched turrets and then automation using one science lab. I added 20 science packs over a period (since I made them by hand) and then I ended up in state where my research isn't completed. If I add another science pack then the research instantly completes.

To explain more: this seems like the floating point numbers adding up to a value slightly less than 1 whereas the real number values would add up to exactly one.

Attached is a save file where this is happening. Just add the science packs in the inventory and the research instantly completes.

This is a known issue that we didn't think would be too big of a problem. As you said adding the additional 1 science pack instantly completes the research.

It is however still a bug so for now I'm going to move this to known issues.

I can more than confirm this, as I built two science labs and 60 Science Pack I and then researched Automation, Logistics, Steel Processing and Optics and the labs have run out of Science Pack Is without completing the research. There is just a sliver, if that, of uncompleted research in the bar. It's no great effort to make one extra SP1, but you know how it is...something either works right or it doesn't.

P.S.: This is in 0.12.3 that it is still happening.

It beats the amount of science packs we used to lose with the old system. :p

Wasn't this already fix? When i start new game i always make initial research with manually crafted science packs and when it said 40 it always used 40.
