Loot tables defined with LootTweaker do not get called on a SpongeForge server

[zediious]

Bug description

Loot tables defined with LootTableTweaker (as defined here https://github.com/zediious/galacticdrive/blob/0.2alpha/overrides/scripts/chestloot.zs) do not appear in chests on multiplayer. An example of this is the chests inside the WroughtBuilding structure on Hilund.

Did this behavior work in a previous version?

Had not been tested on multiplayer

Steps to reproduce

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 results in no items.

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

It looks as though this may be a problem with Sponge, chests assigned with the loot table populate correctly on a server without Sponge. More testing needed.
