I wanted to try the older versions of the Localized Weather Mod and it crashes everytime with this:
java.lang.NumberFormatException: For input string: "planks"
This affects 2.0 - 2.3.5

planks <- is not a integer, thus it creates a numberformatexception

Nevermind, i already fixed it by deleting the configuration file. It was an newer config file and i was using an older version that uses and older config file.
