Issue description
For some reason, simple concrete barriers prevent flipping. I suspect they just haven't had their mirroring data entered appropriately, since they are simple entities that should be easy to mirror.
Reproduction steps
- Copy any set of objects that include at least one concrete barrier (tested with barrier ends and straight segments).
- When pasting, attempt to flip; flipping will be blocked.
