This issue/request is in response to this comment on CurseForge.

Describe the feature you would like to see:
Graves currently decay to the next stage at a random pace (with fresh graves decaying slower than the last three stages), it could take a single tick or thousands of ticks. It'd be nice to have a little more control over how long each stage takes.

Here are my initial thoughts on making the decay rate more predictable and configurable:

1. Perhaps make each stage have a configurable chance weight (how likely they are to decay).
2. Perhaps add a configurable min/max amount of time that needs to pass between stages:
   • Min: The grave won't decay unless the minimum amount of time has passed.
   • Max: The grave will decay once the maximum amount of time has passed.
   • The grave can decay anytime in-between the min/max times.

The features of this issue have been added to the mod and will be present in the next version.
