remote player on pc
local player on mac
tnet server running on terminal using -mono to run the exe on a mac (could this be it?)
remote player shows timed out on terminal.
local player in unity stops playing, codes a little then presses play.
I think this just may be a result of running it on a mac under less than ideal conditions so I'm not in too much of a panic. It has happened more than once though, for example one play crashed, and this also triggered it. It has also happened if I paused unity to check something... so it's vaguely to do with a timeout.
Will just add to this thread if I get a better example. 1.80.
