Aren’t broadcast and multicast two different things?
Good to know that multicast will be fixed, and most likely I will switch to this once it is released as it is probably more efficient for my use-case. (are your referring to this post?)
However, in case one would choose to use broadcast (e.g. sending to 192.168.0.255) instead of multicast, I believe the sender should always receive its own packet, which currently is not happening, but was working on the Core. (Probably one of few things working correctly with UDP on the core ;))
