Please explain your issue is in as much detail as possible.
My problem is regarding the public transports. I tried to illustrate it the best way I could with photos and videos that you can find attached to this message.
The first problem is with the lines. All my stations are perfectly connected with two-ways roads or tracks, when I'm creating the line everything is working well. And then, some par of the line are disconnecting, in a total random way. It's telling me that the stations can't be connected together, and then it's working again normally. If I'm trying to reconnect them manually, sometimes it's working, and sometimes not. This phenomenon is happening on all the types of public transport lines.

My second problem is certainly related to the first one. On the public transport lines, vehicles are disappearing for just no reason. It's once again happening in a total random way and when it's starting all the vehicles arriving at the stop are disappearing during ~3 minutes. The stop is almost always different. This is very annoying cause new vehicles are constantly being generated by the bus or trams depots and creating a lot of useless traffic.

Thank you so much in advance for your help !!

Can you replicate the issue? If yes, please explain how you did it.
Yes, by just creating a public transport line

You're likely hitting the path units limit of the game because of a buggy vanilla asset, the City Quay. See this thread: https://forum.paradoxplaza.com/foru...ines-are-broken-and-buses-despawning.1575492/

Thanks for the reco. I checked the thread and they were having the exact same problem as me.

I deleted all the new quays with trees and downloaded the Transfer Manager mod to erase all the broken paths.
Now everything is back to normal, it literally saved my city.

Thank you so much for your help I was so desperate to find a solution.
