# Number of hearts you spawn with. [range: 1 ~ 30, default: 10]
I:defaultHeartCount=8

# Number of hearts you gain per milestone. [range: 1 ~ 30, default: 2]
I:heartsPerMilestone=1

# Add tooltips to foods to indicate if they have been eaten? [default: true]
B:isFoodTooltipEnabled=true

}`

After eating a food item, the tooltip does not change, nor does reaching a milestone seem to register (i.e. hearts do not increase and no message is displayed). I'm not sure whether another mod I have is interfering with this, or whether it is an anomaly from SOL Carrot itself.

This is not an issue with SOL:Carrot itself, until it can be reproduced, marking invalid.

Sure.
