Upgrading from 8.8.8 to latest 8.9.1 results in dictionary error

[rbbrdckybk]

Just upgraded a basically fresh install of MyCodo 8.8.8 to 8.9.1 via the web interface. Upgrade completed successfully, no errors. After the upgrade, navigating to most pages results in the following HTTP 500 error (I'm new to MyCodo, but vaguely remember creating a custom measurement that I tagged "999" when I was originally looking things over - so I assume the dictionary error has something to do with that):

It looks like one of your inputs may be referencing a missing measurement.

[rbbrdckybk]

That is probably it. I set MyCodo up as a fresh 8.8.8 install a couple weeks ago, and set up a single input to test things. I'm pretty sure I created a custom measurement, and I probably set my input to reference it. Everything has been working properly for weeks, until the upgrade to 8.9.1 yesterday. The upgrade completed successfully without errors, but I can't navigate to most pages now - I just get this error. I'm pretty sure something happened during the upgrade that dropped or otherwise broke the custom measurement.

I'll probably just re-install MyCodo since I didn't have much set up anyway - just wanted to give you a heads up!

[kizniche]

I can replicate this issue. I'll figure out a way to prevent all the page issues when a measurement is deleted that other controllers are still referencing.

[kizniche]

just made a release that fixes the errors on the Input/Function pages when there are missing measurements/units and will indicate there's an issue when the options are expanded.
