(ema) master switches by changing isboxer windows. why?

[Jabberie]

Not changing the master per Mirai (or checking off the jamba management in the character set) is the better solution, in ema there is no point in (ever) changing the master as it doesn’t do FTL, ISBoxer does. (Unless I miss a use case but I never change it and had the same issue as OP initially)

It effects plenty of other things that you want master to be correct in EMA though.

It's usually better to use a tool how it was designed than to break a bit off to suit your current needs.

How about some specific examples?

Not following... break what?

The addon is designed to have the master swap to the character being played.
Stopping that from happening essentially breaks how it was designed to work seeing as there is an option specifically designed to do what the OP wants.
