Suggested Feature

We are building servers with the OTG mod and it is very important to us that the territories damaged by players can be restored. Since //regen from WorldEdit does not work with custom generation, it would be incredibly useful to add a regeneration function.

Suggested Implementation

You can implement it in the form of a command in which you will need to enter 2 coordinates of the extreme points or in the form of an API that other mods can use (1 public method that accepts only the coordinates of 2 points is enough)

We often use 1.12, so we ask you to make a feature for at least this version, but it would be useful everywhere

Anything else?

We really hope for help. We are expecting the appearance of a similar function.
