Settings altered and equipment change

Today I logged in for a group ride and something felt weird. I quit the group ride and started riding something in Watopia. Still felt weird. Checked my settings and my trainer difficulty had changed from 100% to 50%. My mode had changed from ftp to erg. Restarted a new ride and things felt right, but then I noticed my Jersey was orange, a color I’ve not worn for many months. Just an fyi for whoever reads this stuff!
