I was hoping that after the presentation earlier this year and the update to the codebase that MakeCode would become more stable, but it seems like it has become broken. It could be from extensions breaking saving projects. Projects are forgetting code blocks, and having students revert back and rewrite is not acceptable. Tutorials like the Game Maker Guide (with the platform in particular) are bugged on student accounts. My students are constantly getting project conflicts (where it creates a copy of the code base, only for them to be unable to properly save to an PNG). They have had to re-write their code multiple times, due to MakeCode Cloud system corrupting their code project. This system needs to be thoroughly debugged over the summer so that by September it is in a stable position. Sadly most of these bugs (seem to be a product of make code codebase changes of 2025) Last October (2024), there was internal memory limit that prevented my students from saving their work and that was fixed by increasing an allowable buffer. I cannot help but wonder if there are additional internal memory issues now that there is an updated codebase. I am starting to consider abandoning the MakeCode system due to its instability, as my students are losing their progress, functionality is randomly being disabled (for example: the advanced tab with ability to make/use functions disappears but _sometimes_ by clearing the cache and reloading the project you can recover this) or the ability to save a your project as a PNG breaks. ---

Hi @emory55. I am very sorry to hear about all these issues! I would like to take them one at a time to see how we can troubleshoot and solve them for your students. It would be great if you could file issues for each one of these problems in GitHub - [https://github.com/microsoft/pxt-arcade/issues](https://github.com/microsoft/pxt-arcade/issues). In the issue, please provide as much information as you can to help us reproduce the error on our side (platform, browser, link to the project or tutorial, etc.) Here is what I think are the issues you are running into (please let me know if I have these right): - Game Maker Guide Skillmap not functioning correctly - Losing code in projects (using extensions?) - Unable to save project as a file - Toolbox categories disappearing We would very much like to fix any issues you are running into. Thank you, Jacqueline ---

Thank you I would like to work with on this matter. This week it is the deadline for my students, so I am not sure if I will have time to resolve it. My students cannot even share the project via a shared link. The internet access is not an issue as they can work on it and connect to the cloud, etc. My stopgap solution is to remake the project with a vanilla blank project. When my students try to rename their project, it always reverts back to their original name on the cloud. ![PXL_20250617_153922978](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/3X/b/f/bfc83a36388661c900630cbf9e6066e7fd004561.jpeg) ---

Hi @emory55, can you download this program and send the .png file to me? Also, can you paste in the exact URL you are using for Arcade? I couldn’t see the address bar in your photo… Another thing that would be helpful is to send us the browser console logs which you can get to by pressing F12. Here is also a list of some good tips for sending us information on an issue - [What to do when you encounter a bug - MakeCode Blog - Microsoft MakeCode](https://forum.makecode.com/t/what-to-do-when-you-encounter-a-bug/35120) ---

+1 on this. My daughter has been fighting his bug for a month now and has caused her to miss a project. She is now doing her final now and has to do this not logged in and saving via download picture every hour or so to not lose her work (again). As a professional in software development this is exceptionally frustrating, and not the experience we need to be giving to novice developers. Fighting our own bugs is bad enough, but when the platform is destroying your work this can completely sabotage any excitement and joy. ---

There was a fix earlier that automatically pruned the code history which bloated the projects. It would be nice to be able to manually delete those as well (currently this is not a feature). Riknoll’s fix helped to resolve my problem last semester so I am surprised it was not pushed to the production. I will start using MakeCode Arcade again in January, so I hope it can be resolved soon. ---

I pushed out the fix for this today! The latest version of arcade (2.0.60) should prune the history file for any project that is opened, fixing this issue. You can check the editor version by clicking About in the gearwheel menu. The update is already live, but it might take a minute or two for your computer to download it. ---
