Himself closed map editor.

Of course, I’m in vain that I haven’t written about this before, but still. Recently, the map editor itself has been constantly closed by me. Some errors are written in the logs.

And it closes with me when I lay the contact wire. Well, in fact, almost the same spline.

[А у меня она закрывается, когда контактный провод прокладываю. Ну, по сути почти тот же сплайн.]

I don’t even know what to do next ... After this error (I didn’t manage to save the log), all the stretch splines disappeared. How to make them visible again?

UPD: Removed one of the splines and put it back - and immediately all the splines came back.

UPD: Удалил один из сплайнов и обратно его поставил - и сразу все сплайны вернулись обратно.
