Many event buildings give additional resources like FP, goods, sometimes supplies etc. only when the building is motivated. If you open the production overview after collecting your daily production the goods of the Airship will often not be on the list because the Airship is not motivated yet. If you open the production overview before collecting your daily production your Airship will already be motivated and goods will be shown in the list.
In the current release version we also show the FP value under the condition that everything gets motivated before being collected. For example 300/500 means that your buildings currently have 300 FP, but after everything is motivated you will get additional 200FP (so 500 total).
For resources other than FP ()like goods, guild power, supplies) etc. we do not have that feature yet, but it will be included in the next update.
