I get this error when I'm planning very large missions (more than 1200 waypoints approximately) and trying to pair them down to a manageable size.

Once I get this error, I'm unable to remove routes from the program since they show up again after about 30 seconds.  I also can't edit the waypoints either since changes are not saved and show up again 30 seconds after I make them.  Sometimes it just removes all the routes without warning, erasing anything I had not exported.  

The only solution is to restart UGCS or sometimes I need to restart my computer.  Does anyone else have  a better solution?

The computer is fairly capable with a GTX1050 graphics, i7 and 16 gb of ram.  Which one of these needs to be better so I don't run into this problem anymore?  

I also think UGCS needs to be able to handle this error more gracefully and be able to recover without restarting everything.
