Cheaper Engine Maintenance (Event?) and Cheaper Engine Maintenance Worker

  • I don't know if this is a bug or they don't stack but we got the Cheaper engine maintenance (event?) and also have the cheaper maintenance worker and I was curious why the engine maintenance isn't free since they are both 50% off. Am I missing something or they don't stack? Anybody know the answer to this?

  • they are, like all workers, multiplicative.

    So basically, 50% means you pay 0.5 x the price.

    Two of those means you pay 0.5 x 0.5 x the price = 25%. The same is true for, for example : worker + cheaper building voucher, or 2 workers of 2 different eras at the same time.
