So, I'm fixing something for a friend. Among other things it had a few resistors that had drifted somewhat so pulled them and ordered some new ones as part of a big order for an upcoming project. Put them in and then started to test the circuit. Hmmmmmm. Thats weird, those readings are way off. Scratch head and leave it a day. Come back and try again. Same result. OK, thinks it might be something I changed. Grab the bags from the supplier and start checking the spares in the bags. A HA, 22 ohm resistors that are actual 1.6M ohm .... Some new 22 ohm's on the way (I hope). That will teach me not to rush. Or as my father would say, measure twice, cut once.
