whenever I run firmament for 1.21.4 on fabric (i put this issue here because it seems to be a kotlin error, this mod is a dependancy of firmament), I get java.lang.ClassNotFoundException: kotlinx.datetime.Instant error. is it a error in the mod's code, or is something wrong with my setup?
edit: my computer is running fedora linux

See #169 for more info, but I think that this is just a problem the mod author will have to fix
