I created a gravitas server and noticed that my advancements for the terrafirmacraft story tab just stopped at clay forming and get charcoal despite me being into the copper age/almost bronze

So I went onto a singleplayer world to test and tried the command
/advancement grant Pixel1001 until tfc:story/copper_age
and it worked, giving me all of the advancements upto and including the copper age advancement

However on my server, this command doesnt work as the advancement is missing (as shown below)

These appear to be the only story advancements that appear which is strange

fixed (TerraFirmaCraft/TerraFirmaCraft#2313)
