So I’ve had my routines set up for a while now and things have been running smoothly. A few days ago I noticed the living room lamp turning off before it was scheduled. This morning the living room lamp as well as the kitchen sink light turned off about 17 minutes after their scheduled On time. Any other light I manually turn on is also automatically turning off after a few minutes. I have several zigbee lights (the only thing zigbee) and several zwave switches and both are acting up turning off automatically. I’ve changed nothing in my setup before this started happening. I did go in and update my hub thinking maybe that was the issue. I’ve also rebooted it a couple times. This is very annoying as the lights won’t stay on! Thankfully we have lots of natural light but still. Please help!
Alexa user? If so, verify that Alexa's "hunches" feature is off/disabled.
I checked hunches and she has not turned off any lights in a week and even then it was deck lights in the middle of the night. 
I have to agree, this must be very annoying and also, very unusual. Unfortunately, without more details it is hard to figure out where the problem is coming from. I can tell you for sure, that is unlikely related to the latest update as everyone else's lights would act the same as yours. However, if you think the update may have caused the problem, you can always go to the Diagnostic Tool and revert to previous version and if the issues persists, then the update didn't cause it.
If you'd like help in troubleshooting the problem, here is a document that might give you some ideas of what details to share so others can help:

I've had this issue before where I inadvertently created conflicting rules that all manipulated the same device. I understand in your situation nothing has changed but it's good to check anyway. The way I tracked them down was by looking at the device page and noting the apps that used the device, then checking the apps to make sure there wasn't something else affecting the lights. I'd also suggest turning on logging for one of the devices (maybe the one that it happens to most often) and also turning on logging for any app that uses that device.
Even though Alexa appears not to be messing with you I'd suggest maybe turning off hunches until you solve the issue. Just to eliminate possibilities.
