Switching prevention issues.
Using master from 03/24/2018.  Switching prevention set to 0 does not yield the most profitable miner for that run.  As you can see many miner/algorithm combinations are much more profitable.  The problem compounds when switching prevention is set to 1 or 2, to where the miner sits and mines x17 more or less oblivious.

The same thing was happening on the last release version.
