Morning, everyone!
Version 0.9.1.0 adds a much needed change to how workers are assigned to buildings. The problem up until now was this: A building has an ideal number of workers that you have declared should work there. And it also has an actual number of workers, which can sometimes be lower than the ideal number due to the fact that workers have died without there being anyone to replace them.
The old UI just showed a single number - the number of workers currently working at the building - but it didn't show the ideal number. So in the aftermath of a particularly deadly invasion, it could be difficult to understand where new workers would be going as the population recovers.
I've changed the worker UI to be icon based, to show both the number of workers who are actually able to show up at a building right now, and the number of workers that you would ideally want going there. As new workers grow up, they'll fill in the 'ideal' slots until the building is returned to its ideal workforce size.
The Professions menu (the one that lists all buildings and their workers) has also been tweaked to show both the current output of each building and - if the building isn't fully staffed - the output it would have if it had all the workers it's requesting.
I hope this helps with keeping the planet organized and productively employed. =)
