Please report all 1.7.10 bug reports to the FoamFix17 repo instead.

Here's a list of known bug report classes.

java.lang.IllegalArgumentException: Cannot set property PropertyInteger{name=level, clazz=class java.lang.Integer, values=[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]} to 81 on block minecraft:water, it is not an allowed value
    at pl.asie.foamfix.common.FoamyBlockState.withProperty(FoamyBlockState.java:59)

To this day, with the exception of BiblioCraft, I have not managed to find a case where a "Cannot set property" crash was actually specific to FoamFix, and not just blamed on FoamFix because we patch this area of the code. The codepath causing this error mimics vanilla behaviour very closely, and should cause the same crash without the mod installed.

java.lang.NoSuchMethodError: net.minecraftforge.fml.relauncher.ReflectionHelper.findField(Ljava/lang/Class;Ljava/lang/String;Ljava/lang/String;)Ljava/lang/reflect/Field;

FoamFix 0.10.x requires the absolute latest version of Forge. Grab it, and the error should go away.
