Packet loss can happen anywhere, it's impossible to make sure it never happens.
A switch will drop packets, the nodes can drop it if 2 packets arrive too close to each other or it get's busy ....
The tcp/ip stacks that all of us use can drop UDP without warning for a number of reasons.

What I'm saying is because there is no ack, there is no way of knowing that the off frame was ever received. UDP was designed for cases where you don't care about losing packets, in these applications we do.
So there are 2 options either switch to TCP which was designed specifically for making sure every packet got to destination (unlikely) or stream Unicast UDP packets continuously. That way if a packet does get lost it will only be until the next update which would hopefully very shortly after.
