Error on digblock()

Hello,
Why i having this error on try to drop a block using digblock()?

[22:02:42] [Server thread/ERROR] [Sponge]: Could not pass ChangeSignEvent$Impl to org.spongepowered.mod.plugin.SpongeModPluginContainer@3d208e3d
java.lang.AbstractMethodError: Method net/minecraft/world/WorldServer.digBlock(IIILorg/spongepowered/api/event/cause/Cause;)Z is abstract
        at net.minecraft.world.WorldServer.digBlock(WorldServer.java) ~[le.class:?]

The code is:

...
w.digBlock(loc.getBlockPosition(), Cause.of(NamedCause.simulated(p)));
...

I tryed to use NULL on cause and not work too!

AbstractMethodError basically means that it’s not implemented yet.

Shure? :frowning:

Can i make something to make this work or wait to be implemented??

I have a PR open to implement this feature
https://github.com/SpongePowered/SpongeCommon/pull/86

For now, you’ll have to find another way of doing whatever you’re doing without using the simulated methods
