[0.15.x]BP unable place rails on ghosts different force

[I_IBlackI_I]

Sorry for the grammar butchering title.

In 0.15.x you are unable to use a blueprint to place rails on top of ghosts from a different force, all other entities seem to work fine.
See images attached for example.

How to replicate this issue:
1. Place down a ghost entity on a force different from the one you are going to be using the blueprint in.
2. Try to place a blueprint containing rails.
3. As you can see only rails in the blueprint show up red when on top of ghost from a different force.

Thanks for the report.
Fixed for 0.15.7
