Current EA changes that affect this page
Burglary rates were rebalanced. The notes do not provide a universal safe threshold or guarantee that a security improvement prevents every burglary. The hotfix fixes failed quarter-improvement actions and increases AI willingness to invest in improvements against deteriorating quarter values.
Record the effect, cost and delay
Read the improvement panel in your game. Note what changes, how much it costs and when it finishes. The developer’s business diary confirms construction takes time, which means a benefit can arrive after the problem you hoped to solve.

A production upgrade may require more ingredients, storage or cart journeys. Ask whether those are available before spending. Conversely, a storage improvement may protect a production plan without directly increasing output per worker.
