All the older libraries are disabled. But the errors are still there. There are two of them which don't have any errors, 2 and 4 track with overhead wires. The ones that error don't have overhead wires. They are by rrsignal. I wonder if they got broken in newer Trainz versions? Why would those three error but two not? Is there a way to bulk replace faulty assets with working ones? I suppose it's the same way like replacing faulty trees by cloning the faulty assets and doing a kuid swap then bulk replace in surveyor. Also, the errors are not present in 19, just 22 PE. There are other PRR signal bridges by gfisher and norfolksouthern37 that I could substitute, but for the faulty ones on the route from the DLS which is the PRR lines south of Altoona to Cumberland, MD I would need to know where the faulty ones are on the route to know where to place substitutes manually.
