Every time I try to do an asset update I get this stupid message. I'm clearly trying to replace a grade level crossing but this is the message I keep getting. N3V needs to fix this.
MO-crossing assets, meaning road crossings, along with fixed-track objects such as industries and stations, bridges, and tunnels can't be updated using this method. The reason probably has to do with replacing these assets this way would probably break the route due to assets not fitting properly or due to other things such as scripts.
I can't think of a clean way of replacing these assets without cloning another asset and using the same kuid as the original. This creates a mess and can break a lot of things especially if the route gets uploaded to the DLS.
