Just a quick heads up for you all, version 1.3 is going to be uploaded to you all very soon so that you can use it. It fixes some bugs found in the last version, such as the error message 'LFSWorld Error : $str' now it will return that error string for you to deal with. Might change that behaviour in the future.
Big fix on the get_wr, hotlap_chart functions. They should now return the correct name for racername. Also I've modded the get_hl, and get_pb functions to make use of the same function set as the other two. Keeps the code nice and homogeneous.
