Please send the log as my only thought is that it is happening when there are more than 1 type of GPU in a system.
For example I have 1 mixed system that i setup today with a R9 270x and a R7 360 and each mines a different algo when the dev fee kicks in only one of the 2 is switching to the dev fee which is still fine by me.
As to the donation and how it should be working
After the first 3 Hrs it should switch to the dev address for 12 Min then switch back your address and reset the timer for the next Dev mining for another 12 Hrs.
Just sent over the log. I do have 1 1080 ti and one 1070. Both of mine ended up switching though. Perhaps because I cycled the miner mid change? Thanks for explaining how the schedule works.
No problem, I will look into the logs tonight and see what I can find.
