I have a lot of times where I am executing one database over another just to get a few items or spawns etc... It takes forever (a few hours) because of all of the errors.
I found out that the errors only slow you down if you are watching them roll down your screen. Instead of staying in the "Message Log" tab at the top ofthe execution window, switch back to the "General" tab.
Ta da! Your navicat execution goes about 6 times faster!
