The TContruct Plugin throws the following error in the 1.7.10 version:
[23:08:48] [Client thread/WARN]: Something went wrong with TConstruct Plugin at INIT Phase
[23:08:48] [Client thread/INFO]: [java.lang.Throwable$WrappedPrintStream:println:-1]: java.lang.NullPointerException
[23:08:48] [Client thread/INFO]: [java.lang.Throwable$WrappedPrintStream:println:-1]: at mariculture.core.util.Fluids.getFluidName(Fluids.java:61)
[23:08:48] [Client thread/INFO]: [java.lang.Throwable$WrappedPrintStream:println:-1]: at mariculture.plugins.PluginTConstruct.init(PluginTConstruct.java:70)

I believe this is because it is trying to register the fluid "aluminumbrass" instead of "aluminiumbrass".
