Chief Hiawatha have 2 x Food Skill Research Time, but only the first one work.

I try to do the second "Food Skill Research Time", but not change in my research time (for food), and it did not affect the one for gold also....
Anyone else have the same "bug" ?

Both skill have the same "name" and description (in both English and French)....

I have 2 accounts both of which have completed 5 tiers of the Hiawatha reduced food training time. Like you said, I have not noticed any reduction at all past the first one.

I have tier nine shooter dps(normally 10 days)going simultaneously and it has been ticking down normally despite completing 4 more Hiawatha researches since I began it.

Same here... see no change in shooter and howitzer Training time despite completing the last "box"...

Turns out it gives it to you. But only when you begin a new research, the bonus doesn't apply to ongoing ones. Which is weak sauce, but not surprising sauce.

I've noticed you often have to reload the game for the time changes to be reflected.

I think the last update have correct the problem.
