Issue description
Here's a screenshot of my unity screen after building tomb of captains with only lvl 1 housing

And here's one after upgrading to lvl 2 housing

Notice the unity addition remains the same in the upper left but the unity breakdown screen doesn't report accurately.
Expected behavior
Unity bonuses from tomb of captains to be shown correctly before upgrading to lvl 2 housing
Reproduction steps
- Load attached save
- Look at unity breakdown screen
- Upgrade one housing to lvl 2
- Look again at unity breakdown screen
Game version
v0.4.11
