It's a new BP (only 2 update version old) and I don't do Search & Replace that early in BPs. Those Rotators where probably within the 1st 100 blocks (no logic at that point). I did however create the docking from the 'creating docking' in advanced build mode.

Stripped down problem from the original.

Drat. I gutted the original BP with the problem and my tiny schematic does not duplicate the error. I had been able to determine that the rotator did not disappear if I removed the pipe.. but the error reoccurred if I put the pipe back (I was trying to make sure I had not linked it in some bizarre way).

Try this one

The 'NOT' was a correct as my 1st message had a typo (did instead of did NOT)
I was using benches UDP template when I noticed the oddity then made a few more template and it appears to be a consistently occurring error.

Bandwidth is over 1Mb/sec and it lets me download torrents so I imagine multiple connections are OK (sometimes connected to 25 peers at a time)

Tried another of the same type of phone (OnePlus One) and the results were the same, working but a strange startup sequence (and slow).

How do I attach the log file?

server.txt.0 (again clean before trying)

ISP is unlikely the problem, I can do all sorts of naughty things without a problem. Trying to figure out how to attach the log files as Feedback.
