Players invisible when sending multiple of them to a server

Hello,

we are experiencing some troubles when sending multiple players to a server at once. Some players don't see others or see them without skin.
It might be possible it's a client-side bug and I would be open to a solution which doesn't requires an update of BungeeCord, such as re-sending player info packets, but I don't exactly know how to do that.

Can somebody provide help? Would be nice to see that fixed.
Thanks in advance
