Which blocks are you referring to when you say a "v1" and "v2" block?

What do you mean by a v2 block? Could you provide a screenshot of what you are trying to do with both the "v1" and "v2" blocks?

As an update on this front, I have made some improvements to both make NetsBlox more robust to flaky connections as well as make it easier for users to recover if they encounter this error (click to reload the project automatically). It should be available on editor.netsblox.org within the next few days.

Happy holidays!

Gotcha. Thanks for the extra info! I suspect the internet connection is part of the cause but I will look into making NetsBlox more robust in the presence of flaky internet connections.

In the meantime, I would recommend the student who is able to edit the project saves the project then have the student experiencing the issues reopen the project. If the project isn't saved before the student reopens, the student will open the last saved version and then try to fetch the actions from the collaborators (which appear to be missing).

Let me know if there are any other issues!

Good idea. I will add this to the roadmap.

Hi @coconut,

That is actually the copyright and doesn't necessarily reflect the last update. They should be in sync but currently are not. If you are interested in checking out the latest updates and releases, feel free to check out https://github.com/netsblox/netsblox for the server updates and https://github.com/NetsBlox/Snap--Build-Your-Own-Blocks for updates to the client code. These links actually contain the source code for the project itself; NetsBlox is open source so the code is publicly available.

The version of NetsBlox hosted at https://editor.netsblox.org should always reflect the latest released version of NetsBlox (though there may be a delay of a day or two from the release date). If you are interested in the releases, they can be found here along with their release notes. As @topgamerpro16 mentioned, I am planning on making a new release soon with a bug fix for the duplicating comments bug he found and reported. It will contain a few other minor bug fixes and improvements but should be minor small.

Thanks for the heads up about the incorrect copyright year! I will get that updated so we can avoid this confusion in the future!

What is the context? Could you share more about what you are trying to do and why you need to call a block in JavaScript?

I made an issue on GitHub (where the NetsBlox source code lives). Feel free to follow along there as I dig into it on my end: https://github.com/NetsBlox/NetsBlox/issues/2923

Has he been collaborating with another student? If so, could the other student save the project so he can reopen it? How long have they been collaborating? It's also possible that this could be caused by a flaky connection while working with a collaborator (if both collaborators appear to have disconnected at once).

If you are interested in a little more background:
When two users are working collaboratively on a single project and one disconnects for a little bit, his/her computer will try to request any edits that it missed while it was disconnected. In this case, the disconnected computer was not able to fetch the missing actions.

I have some suspicions about the cause (I suspect it is related to flaky internet connections) and will dig into it! Thanks for letting me know! Let me know if saving and reopening works.

Makes sense. This has been requested before and is definitely being considered!
