If I apply multiple liveries to the same plane, e.g. mail plane (10% speed) and celestial plane (500% income) do those bonuses stack to give me 10% speed and 500% income?
If they’re different in effect yes (the example you gave) . If they’re of the same nature, no (eg 10% speed over 40 % speed results in 40% speed. Highest % wins)If I apply multiple liveries to the same plane, e.g. mail plane (10% speed) and celestial plane (500% income) do those bonuses stack to give me 10% speed and 500% income?
