Hi @mhered, thank you for raising such a detailed issue. I would like to get a few more details as I am unable to reproduce this issue on my end. I request you to follow these steps so that I can gather some more information to understand the root cause of the problem:

1. Run atri start --debug to run atri editor in debug mode.
2. Click Build & Run.
3. Copy all the logs generated in the terminal and please send it here in the comments.

Again, we really appreciate the effort you are putting into it.

Hi @mhered. I was not able to reproduce the issue on my end. It would be a great help if you can push your project to GitHub?

[mhered]

Done, you can check it out here: https://github.com/mhered/calcount2

[mhered]

As mentioned it is almost empty, only has a page with a div and a table, and no backend

@mhered Thanks for sharing your repo with us. I was able to figure out the issue. It seems you had two instances of Atri Editor running parallelly in the browser for two different projects. The events from one project have seeped into another, hence, the state of the app cannot be computed. In the next version, we are going to add guards that would prevent this from happening. Thanks for sharing your repository. It was very helpful in figuring out the root cause of the issue.
