Incorrect crop output

My have 4 level 3 fields in cropland but my crop output 48per hour and NOT 168 per hour as it should be. Please fix this.

Are you sure you don't have troops? Troops reduce the crop output because they have to eat. If your crop (not crop output) reach 0 your troops will die.

Yes, I do have troops. How much crops do troops need?

For every troop.

Inf : 1 crop per hour
Cav: 4 crop per hour
Arch: 2 crop per hour
Cat: 10 crop per hour

Thats for every troop so say you have 10 cats thats 100 crop per hour.

Edit: BUT to make math harder. The planting tech makes Crop output increase by 10% each Level.
