How do I fix lft and rgt in mosets tree?

I am using Mosets Tree 2.2.0 in Joomla 1.6.1.

I find that from time to time, the nested model left and right indexes bleed into each other and cross boundaries they shouldn't, I have tried recounting the category indexes which does not fix the issue.

I can easily fix the issue by manually resetting the the left and right indexes in MySQL so that they match the correct tree structure, but, we have allot of categories and I don't want to be doing this every time as it is time consuming. So my questions are:

1) Why does this happen?
2) How can I prevent it from happening?
3) How can I fix it quickly when it happens? (I could write an automated query that fixes lft and rgt to run daily, hopefully the answer is easier than that)
