Describe your issue

When using the server script to modify chest loot tables, if the loot table address does not start with "modid:chest," then kubejs will automatically create a new loot address. Example:
My script is event.modify("betterdungeons:spider_dungeon/chests/egg_room", table => {})
This will not actually change the loot table at "betterdungeons:spider_dungeon/chests/egg_room" but create a new one with the modifications at "betterdungeons:chests/spider_dungeon/chests/egg_room". This means that upon world generation, only the original script will appear, unmodified.

You need to use the generic loot table event if the mod does not use Minecrafts loot table path conventions.
