not often, Viz actually screws up more than Funi
that said, Funi is kind of having a shaky experience with their sudden decision to support LGBT rights
they're a tiny bit overzealous and making odd decisions with said shows
like Removing the Gay lines from Dragon maid (they were jokes and in some contexts could be considered homophobic jokes but still)
that said if they add lines retconning the boys from Free! as actually being Gay in the dub I'll forgive the few mistakes they've made because the only thing wrong with that show was Kyoani's insistance that the boys were not Gay after all the blatant Gay subtext
