Relax. Take your time. Grandpa will only evaluate your farm on request. When year 3 comes, nothing will happen.

When you're ready for your first evaluation, place a diamond on the shrine. Subsequent evaluations continue to be available in the same way.


Configuration:

SkippableShrineCandles
SkippableEvaluation1
SkippableEvaluation2
- default: false. If enabled, makes these events skippable.

GrandpaNote
- default: notifies the player of how to activate the shrine. If set to null (without quotes) will leave the note unchanged from vanilla.


Advanced Configuration:

EnableAlwaysActiveShrinePatch
- default: true. This enables the shrine to accept a diamond before the first evaluation, at any time even before year 3, but (not tested) may cause unwanted multiplayer data updates before and after interacting with the shrine. As long as your save has already had the first evaluation, if necessary, this can be set to false, and the mod will still work.
