Session freezing when undoing anything or changing the ground height?!

[trainzboy88]

Hello everyone. I have recently downloaded the latest SP2 update, and now my sessions are breaking whenever I undo something, or try to change the ground height, your game just freezes and you can't do anything?
It's really weird, because I can see the grass still moving/waving on the map still. But I can't do anything else.

If anyone knows how to fix it. I'd love to know! Thank you!

Thank you.

Some things to try:
1. Edit route, make a small route change (e.g. adjust the terrain a small amount) and use Save As to create a copy of your route.
2. Now exit that route and create a new session for the route
3. Check if you can reproduce the freeze (if not, your session is the problem, if still having problems, the route is the problem)
4. Create a new route and see if you can recreate the problem.
5. Try different areas on your route (perhaps it is an asset near where you are editing)

If you can reproduce the issue please send full details in a bug report here: Trainz Bug Report
