After an update, I can no longer playtest my game.

Thank you for any help!

I can deploy the game just like always with no problems, and those deployments work just fine, but when I try to run the playtest function within RMMV, I get an error message saying the file has either been moved or deleted.

Is this something I can easily fix?

Can you post a screenshot of the error message? What does it say exactly?

Thank you for the response, here's what I'm seeing:

@Slotti_Bartfarst as stated in the update topic you need to update your project core as well.

The editor of 1.6.1 can only initiate playtests or battletests if the project's core is also version 1.6.1.
If you cannot update your project (perhaps because of plugin incompatibility) then you need to downgrade your editor again to 1.5.2.

There were several critical changes in the core of 1.6.1, that is why this is needed and why some plugins are no longer compatible with 1.6.1

Thank you Andar, I have been very involved in something for a while now, and haven't been able to keep up with the changes. This program is handled differently under steam than any other game, and I don't see the updates as readily.

I'm currently looking to try and see how to update my core. I do not use any plugins, so that should be no problem.

[EDIT] I started a new project and copied my data back over, and I still can't load my playtest. I can only deploy, and playtest that.

So now there's no choice but to downgrade, at least for this project?

then you made a mistake copying over the files.
check the topic linked in the banner of this site about the current update for instructions on how to update your project.
If you follow that description correctly, then you will be able to playtest under 1.6.1 - that error only happens if you either
1) forgot to copy a required file
or
2) accidentally deployed into your project directory.

please check: does your project directory contain a www folder? if yes then you made the mistake of deploying into it and you need to repair it in a special way.

If you have no plugins, then when you copy your files, do not include anything in the js folder. That's where your core files are, and I wonder if you accidentally copied those over as well?

In your error message screen, there is something interesting, the program is trying to playtest from "www/index.html".
The entry point is controlled by the "package.json" file.

• Could you please open the "package.json" file in a text editor and post a screenshot of what it says?

As Andar stated, this could have happened if you deployed into the same directory as your project, and thus, overwrote your testing package.json with a deployment package.json.
