Due to fast work by Sutorix in fixing a couple of lua error issues with the existing Fishing Buddy release when used on the MoP Beta, there is now a new beta available that fixes these and brings most of the functionality from live.
Still some issues with new zones etc. which is to be expected (mostly related to requirement for updated Tourist Lib) and a few other querks, it otherwise is working and recording the new fish species, catch numbers and percentages, and does note zones though not for all functions. It can be found here;
Thanks for the quick responses Sutorix.
