Hello! I'm sorry to hear you've been encountering these issues, and I apologize for any inconvenience caused.
Thank you for the attached screenshots and your detailed explanation.
Indeed, I was able to confirm the error you've mentioned, and I've already implemented a fix and updated the plugin, which should resolve the issue.
(At least the part regarding the Input Name, as this occurs even without other plugins installed.)
It was a strange bug, and I’m not quite sure why it affected that particular scene since I haven’t used that scene at any point. However, the important thing is that I was able to identify the problem and resolve it (or so it seems, at least).
I invite you to update the plugin to version 1.0.1, which should fix this problem and includes a minor additional feature.
As for what you mentioned regarding:
"There is another TypeError: this._shopGoods is not iterable. This happens when you try to spawn in items via the Visustella playtest effects"
I haven’t had a way to test this since I'm not sure what feature this refers to. Also, please remember that all Visustella plugins are encrypted, so I don’t have a way to read their code for analysis.
I hope this helps, and I remain at your disposal.
Best regards!
