...
maybe you cancelled "first_update"
select the name with no hunters, then click config, then choose colour, then press ok (wait a few blocks.. like 5 )
if doesn't work, restart client
if doesn't work, restart client with -rescan
if doesn't work, it's that Chronos guy

we are looking into avoiding him
After hitting "config" and picking a color, my hunters showed up under my new entity after some number of turns that I'm unsure of.
I've tried this and it's not working for me.
I have 1 player trapped for 15 hours or so (guessing), and another 2 trapped (not spawning) for about 3 hours. Tried multiple times. No luck so far.

Not sure if that info there will help out.
