Simple Missing Replacer

Backup your world before using this!

This mod may be helpful, if you want to uninstall some mods, that added new ores to your world.

The mod transforms all blocks from removed mods to andesite. It's simple, but also can save your performance, eliminating holes, that would appear after regular removal of ores.

1. Close your save with ores in it.
2. Install this mod.
3. Uninstall ore generating mod.
4. Play your save.

It will replace all occurences of all unknown blocks with placeholder in playtime without any lost of perfomance.

WARNING: This mod currently designed to replace ORES only. If it finds other kinds of missing blocks, like mechanisms or plants, it will replace them with andesite! So use it only when you want to remove ores and small amount of other kinds.

In the next updates, it will become more intelligent and configurable.
