What steps will reproduce the problem? Not sure if this is reproducible without dumping my fish database.
1. In Deepholm: Needlerock Chasm (never fished here before)
2. Fish up Albino Cavefish fine, adds to tracker fine.
3. Fish up a Sharptooth, receive error below, does not immediately add to tracker, but DOES go into the database.

NOTE: I just heard from my husband, the first time he went fishing in Uldum and got a Murglesnout he received the SAME error.

What version of the product are you using?  v.0.9.9e4Beta4

Do you have an error log of what happened? Yes.
