So I wake up today, and check my main rig, and it's mining tribus at a really low profit rate £4/day on 4 1080ti rig

Checking the pool it's near the bottom, with neoscrypt, x17, nist etc all at the top
I have no idea why, tried restarting but it went back to tribus, checked all the algos were selected.
Switching set every 20min at 1% diff.
AM 4.31 using ahashpool.
Benchmarks fine, but redoing them.
Anyone else had issues with AM sticking on one low profit coin for no reason.
