Plugin not detected

[sinful mason]

i was install some plugin from some discord and try install by myself. and accidently the plugin is outdtaed but i just try changing the file format from .plugin to .mpf and saving it on managed plugin folder. and now all my plugin was install from store is gone

i was checking, and my managed plugin folder is not read by game

you can't just simply change file format

but I don't know how to convert that to mpf
