I have started experimenting with the Profit Switching functionality, but am having an odd issue.  Again I'm only doing this on a single small rig with a single 1050Ti for now until I get the kinks worked out.  I have these algos configured in the profit switcher:

ETH is the most profitable (and what my other 13 GPU rigs controlled by AM mines, especially the 1080Ti rigs running the ETH pill).  At any rate, this test rigs starts out on ETH as expected, but after a while, it switches to one of the less profitable algos.  If I then stop the rig, un-check all but Ethereum under algos and restart, I get the following error:

Not sure why I would get that error.  All the other rigs are happily mining away on that same pool.  If I shutdown AM and restart it, it starts working again, but the same thing keeps happening.  I can stop and start mining on any of the other rigs, and they don't have this error.  The other rigs are also running Managed Profit Miner profiles, but only have the Ethereum algo selected atm due to this issue.

I only have the NiceHash pool configured under Options/Profit Switching although I do have various other pools defined under Options/Pools.  Here are some of them:

I used those when I was manually switching between algos using Regular Managed Miner profiles.  Could that be somehow causing the issue now that I'm using Managed Profit Miner profiles?  I'm running the latest 5.2.5 version btw, including the Remote Agents.
