Feature data point missing

I have an interesting problem. While tuning a model and looking at historical data with the preview function I started getting the warning “There is feature data point missing” in the sample feature output graph. This hasn’t happened before, my indices seem to be exactly the same, but now this appears whatever I do.
Googling the exact error message yields 0 hits. Does anyone have any input on this?

Nobody has seen this issue before? :frowning:

This looks like a bug. Could you detail steps on how to reproduce the error? You can also report it here: Sign in to GitHub · GitHub
