Hiya! Just a simple issue for adding tags to Ancient Sand.

1. Add the #forge:sand tag to Ancient Sand
2. Add the #minecraft:smeltstoglass tag to Ancient Sand
3. Add the #minecraft:sand tag to Ancient Sand
4. Add the #minecraft:sand tag to Suspicious Red Sand

Here is a CraftTweaker script to do this for anyone who runs into incompatibilities with YUNGs Better Caves and other mods.

<tag:items:forge:sand>.addId(<resource:yungscavebiomes:ancient_sand>);
<tag:items:minecraft:sand>.addId(<resource:yungscavebiomes:ancient_sand>);
<tag:items:minecraft:sand>.addId(<resource:betterarcheology:suspicious_red_sand>);
<tag:items:minecraft:smeltstoglass>.addId(<resource:yungscavebiomes:ancient_sand>);
