Not really sure if this is a bug...
Started some marketing in a number of cities. Afterwards I went to human resources to hire the staff to do it. All the cities had an average wage of 11 (pounds/dollars/EUROS?? can't remember the currency!). A few turns later I started some marketing in another city. Returned to human resources and was surprised to find that all the cities now had an average wage of 38! I hired new staff at this rate. Returned the following turn to find that the averages across all the cities had dropped to 11 again.
(I had hiring and wage setting on manual).
