Hi all, I assume there is a bug when I tried to do the Tutorials – Simple Extensions I have follow the instructions with steps on this Tutorials, but failed to make the game successfully to run on the condition step – when “player” overlaps “object” at location. Here is the linkage for the game: [https://makecode.com/\_dgR8sEKr3Azy](https://makecode.com/_dgR8sEKr3Azy) I have checked the root cause, and found the following, and I think it is a bug that the desired object was not able to save into the source file, which made the code incorrect; the appearance from screen is not what it is in the source code stored in the server. My questions are the following: 1) Is this a bug or I make a mistake (please let me know the correction)? 2) if it is a bug, what is the way to fix it? Is it possible to choose a lower version, which is more stable? Here is what it looks at the editor screen (combination of pic 1 and pic 2) Here is what stored in the server as I believed, after I published and shared the code, I opened the link, and it showed up like this, the object 2 was stored here, instead of object 1, which is the required one. ![图片](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/2X/0/0c91858187ca042134030dbe89f5d073a17e28ed.png) Thanks in advance.
