Hello!
- At the moment, I can't replicate the issue that would cause the tool to miss the package.json file. There might be an issue with the path to the output folder that could throw off the tool.
- Huh... The compression option skips the dragonbones folder by mistake. Fixing it now.
- I can't say for certain what could go wrong with the game not booting properly, since something could have gone wrong. Which version of RPG Maker are you using? What options were you using?
While I'm looking into the issues, please send in the logs that the tool creates. You can use the Migration and Diagnostics Assistant (it's in the Downloads page) and click on Extract Logs. Compress the logs into a zip file and send them to me, either via Discord (aceofaces) or via email (studioace [at] outlook [dot] com [dot] gr).
