Don't forget that plugins are optional and can be enabled or disabled as desired.
This has been mentioned before, but it seems necessary to reiterate. Yes, plugins are connected at will, but the peculiarity of Freshmod, as I understand it, is the desire of one player. That is, it is not required that both players connect the plugin and that they have the same version. Moreover, people started writing about this point immediately after the second Freshmod was released, but what happened next? Instead of solving this issue – which is extremely important for online play – a third Freshmod is released.
