Usually, the formula for troop reinforcements is
Base value (depending on the unit type) x world speed x level of the individual game progress x reward level
For example: When I receive a manticore troop reinforcement level 1 on zz2, that means
1 manticore (base value) x 4 (world speed) x 4 (individual game progress) x 1 (reward level) = 16 manticores
As it seems, in this event the troop reinforcement rewards are calculated without considering the individual game progress level.
For example: The "Daily Special" manticore level 1 troop inforcement on zz2 brought me
1 manticore (base value) x 4 (world speed) x 1 (reward level) = 4 manticores
Is this intended or is this a bug? We had a bug like that in event recipe books before, if I remember right.
zz2 (game speed 4):
zz13 (game speed 3):
