Version checker - upgrading SS4 project to ORD

Hi,

Has anyone done upgrade from SS4 to ORD using version checker? I'm running tests and come across the issues that although corridors seem to be preserved they miss the following:

1. Point controls lost link to Plan Element
2. The component meshes don't display, just linear features (checked corridor FD, levels etc.). They do display only when I change component name. Weird.

Thanks,
Krzysztof
