Hello. I was using the module (the latest 3.1 version posted on mediafire) over the last few days and I did notice a lot of crashing. I think it is a very well-done module with good functionality, and so if the authors were planning to do further debugging, I wanted to share my observation since I did not see it mentioned in the thread so far.
While working on it, I noticed it crashed when rolling the mouse across territory borders - not particular ones that I could pick out, but just when it checks the territory info. Sometimes moving the mouse in the opposite direction or back and forth would do it. If I had to guess based on experience, I would say the crash may have something to do with the mouse rollover components in the module.
I hope that is helpful information. Thanks for the module.
