Something like this happened to me as well:

I had a book with two upgrade planners, the book was added directly into game blueprints and the planners directly in it. Cycling through the upgrade planners cycled the planner name but not the planner icon and actual contents of the planner. After ...

The help statement can come from the character itself (i.e. "I need to build a lab and provide science packs..."). I wouldn't mind ...

One thing that makes a huge difference with the monolithic builds (all cpp files in one) is the optimization level. As the compiler needs to regenerate all the machine code, you don't want to give it too much work to do. On one of my projects I had gcc -O0 at 4.5 seconds, gcc -O1 at 10 seconds and ...

I used the following workaround for long compile times when developing some small games (granted, factorio is much more complex): I combine all my cpp files in a single file (either with cat or #include) and I compile them as a single source. This way you only pay the cost of library inclusion only ...
