Using the latest version here on github:

already installed the virion here
It does work tbh ingame, but it doesn't stack the spawner and the mobs (already set to true in config) but it does spawn the mobs
one shot 1 kill doesnt work too

You need to use the .phar provided on poggit. Dependency injections are handled by poggit, hence the missing UpdateNotifier class
