[1822CA] Game freezes on ICR tile lay

[Lime-Turtle]

ICR is trying to lay two yellow tiles. First on no problem. Second lay allows me to select tile (gentle bend large city) and rotate (heading SW) but then freezes at green tick / Red Cross moment.

iOS by phone and by Mac.

In game 191569 ICR is attempting to lay a 57 tile on hex AN6.

This doesn't completely crash the interface, if you leave it for a while it will eventually complete the action. It took just under five minutes to finish on my desktop computer.

Here is the debug log that was produced. It's the destination check that's taking all the time, for some reason there were more than 22 million calls to node.walk despite ICR being in a part of the map that isn't connected to much else.

When trying to call the JSON Api endpoint a 502 error is given. The same thing could also be happening server-side.

Game https://18xx.games/game/194826 suffers from the same bug. When cloned the game can be continued, even though the CPU usage spikes for a few seconds.
