I'm not sure when or how it happened, whether it was a consequence of the map starting in 15.2 and being opened in 15.3, or some other weirdness, but I'm now at a point where basically the game has 'lost' 1% of a red science pack somewhere.

I'm playing a Lazy game, where I've gone out of my way to only hand build the minimum number of items (now 105).

I've researched:

Automation
Electronics
Automation 2
Logistics
Steel Processing
Optics
Turrets
Stone Walls

And I believe it was in that order. First three I'm sure about. Fourth and fifth I'm pretty sure about. Last three I'm not completely sure about the order, but I think I noticed the problem when I was researching Optics (with Turrets and Stone Walls) not researched yet.

So I haven't researched much.

To give an example of the problem, right now I'm researching Military. My research bar is *full*. Completely. Obviously not so completely as to actually finish the research, but it's reached a point where if I drop another Red Pack into a lab, 1% of the pack later, the research completes.

Somehow, something got rounded when it shouldn't. Or something like that.

I don't know how to replicate the issue, nor have I tried (limited time), but I thought I'd post this just in case it helps direct attention to the problem to stop it in the future somehow?

Attached logs may not be relevant, as I've closed/opened the game since?

This is a known issue with science pack consumption. It uses floating point numbers and there's only so much precision resulting in very small inaccuracies over the course of different researches.

You'll just need to craft an extra science pack every few thousand consumed.

Is it expected after only 190 packs?

Yes.
