I've hunted through a lot of the other tickets here, and found a bunch with the same situation, but unfortunately none of them provided a solution.
When creating a new world, the servers scripts say they ran, but they've not actually done anything. I've got to use /reload or just relaunch the world. It's fine afterwards, just on that initial world generation. Unfortunately, the only potential solution I found on here was to set allowAsyncStreams to false (which I did) but that's not resolved the issue. Someone else showed that they can run a delayed /reload to force everything to load again, but that automatically removes everything in curio slots from the Curios mod so it's not an option for me.
Any help would be greatly appreciated! <3
i don't see any mods that may cause the issue, none that we know of anyways
