if I press the train log gui button that happens

I am experiencing this as well. Any time I press the "Show train log" button (at the top left), the game crashes with the above error. Playing on 2.0.21

Dear @zomis,

I'm also getting this error, when tring to open the log window.

Kind regards

Leon

Are any of you by any chance holding SHIFT while clicking the button to open the GUI?

I realize now that there's an issue that occurs after Flib changed their API which makes this mod break when shift-clicking the button. I wanted to support having multiple windows open but that just got a bit trickier it seems.
