Reccomplex working perfectly in Single Player -- yet gives me errors every time I try to run a server??

[ghost]

Hi all,

Truly an incredible mod. Works perfectly in Single player.
However, I keep getting the same error:

Description: Exception in server tick loop

net.minecraftforge.fml.common.LoaderExceptionModCrash: Caught exception from Recurrent Complex (reccomplex)
Caused by: java.lang.NoSuchMethodError: net.minecraft.world.biome.Biome.func_185359_l()Ljava/lang/String;
	at ivorius.reccomplex.utils.expression.BiomeExpression$BiomeNameVariableType.lambda$parse$0(BiomeExpression.java:57)

Here's my full crash log:

Finally, it definitely has something to do with my Structures files. When I empty my Structures, the server starts just fine. However, I NEED these structures. Why would they work in Singleplayer, with the exact same mods installed, but not on a server?

Thank you so much for your time.

Please please don't let this die!!

I think it might be that you use a feature that's broken, that's not used in the rest of the mod right now (biomes referenced by ID, or something). Perhaps you're on the wrong version of MC. In any case, unfortunately I'm not maintaining the mod anymore. But somebody else might pick it up, if we're lucky :)
