Describe the bug

Loot tables defined with LootTweaker do not appear in chests on multiplayer servers that have SpongeForge installed. Testing on a normal Forge server results in the mod working correctly.

To Reproduce

Steps to reproduce the behavior:

I've tested this using my modpack, although you can of course test with whichever setup you have. If you want to use the same setup, here is the latest release

1. In singleplayer with cheats enabled, use /setblock ~ ~2 ~ minecraft:chest 1 0 {LootTable:"gdtable:hilund"} and see the loot table populate the spawned chest. One can also find or spawn a WroughtBuilding recurrent complex structure.
2. Doing such on a multiplayer server with SpongeForge installed results in no items.

Expected behavior

The chests to be filled with loot. The loot tables are generated properly within the server world at /world/data/loot_tables, and CraftTweaker reports no errors from the script, so I cannot understand why they are not called and populating the chests.

Additional context

I commented this information on an already closed issue, however decided to just post a new issue as it's quite old.

Sidenotes on your script:

• newTable() returns the table it creates. You can assign it directly to a variable, instead of calling getTable() afterwards.
• addItemEntry autogenerates loot functions if the stack has metadata, size, or NBT.
  hilundPool1.addItemEntry(<mekanism:dirtydust:2>, 32, 32);
  is the same as
  hilundPool1.addItemEntry(<mekanism:dirtydust>, 32, 32, [Functions.setMetadata(2, 2)], []);

Thank you for the scrutiny :) I'm not sure what inspired me to use a metadata function instead of just putting it in the ItemStack; I’ll definitely improve the script more when I start adding the rest of the tables.
