Hello, how are you?
Remember that this plugin is an adaptation of an old plugin from another author, so there are certain features that cause inconveniences, I personally recommend you use the following plugin:
https://rabbitteaparty.itch.io/nekogakuen-steamworksapi
It has many additional features, and I think it works a little better for certain things than SteamLink.
Try that and let me know how it goes :)
