It was working fine until I've changed position of my board tiles on the layout. Then this error starts to pop up. I tried to undo my changes and play a lot with different settings for width and high in LayoutToBoard and SquareTX but it didn't help.
In the file below I've removed everything. All unnecessary layouts, layers, object and events.Here's the .capx
It only works - but without moving sprite to target tile, when you disable
