Hey, i already answered on discord, but will put an answer here for other people to check it out.
Will this plugin have BUG when I pack the game?
It shouldn’t, we have tested the plugin A LOT, but there’s only a finite amount of testing permutations that we can do. Nevertheless we prioritize bugs when they do appear. As a general rule though, we don’t go selling things we know won’t work.
What is the latest version of the UE4?
The latest ue4 version, as of now, is 4.19. If you mean the plugin version, there’s a “info” section on the plugin page that precisely explains which version each plugin is available for.
Cheers
