Sponge Forge Advancement Issues?

Hello there, I’ve been searching for the last couple weeks to find something on this to no avail. So I figured I’d make a post.

On my sponge server I can’t seem to get advancements to function nor custom advancements. After about a month of trial and error, I was able to figure out that the problem seems to be sponge forge. If I run my server without sponge forge with mods or without both standard and custom advancements work. But if I add sponge forge into the mods folder with or without mods or additional plugins all the advancements I’ve had to that point in game disappear and any further advancements won’t trigger. I get the same result if I build a completely new server from scratch and add sponge forge, all the default advancements no longer trigger. Is this a known issue or is there something really dumb that I’m doing wrong? I would love some help on this!
