Hi @RoBo !  
 ![image](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/2X/2/2850cc57a14dcca748d83a70d5d5ac1b3c96c407.png)

As showing in these blocks, after you go through the pruple portal, the new tilemap has been be set. But then, you placed myself onto the blue tile, that triggered the “on player overlaps blue tile”, and tilemap be replaced with a empty one.
