Issue with Lilb's 0-6-0 camelbacks

[chickenlover]

I'm having issues with these two locos. The reading branded version makes itself and it's contist invisible while the undecorated model does not allow me to save a session/route. Can somebody shed some light on these strange and annoying occurances with the two locomotives?

Could you shed some light on loco errors.

Actually, there are no errors on the locomotives. But somehow they act like they do.
