11/08/2023, 11:29 AMHey guys! Has anyone had "Error running analysis: ZeroDivisionError: division by zero" in the experiment UI? The experiment had been working fine for a month until today and then the analysis just broke for no reason.

Hi Vladislav. We made some changes to the stats engine yesterday and it looks like you ran into an edge case with the new code. We'll take a look and fix it today

11/08/2023, 5:27 PMHi! Sorry about this. We should have rolled back the bug. To help me understand the root cause, is there any chance you can share some information with me?
1. Are you using GrowthBook for feature flagging?
2. If you are, can you show me the Targeting panel on your Overview page?
3. If you aren't, can you go to Overview, click the three dots in the top right, click "Edit Targeting /Rollout" and show me the coverage and variation breakdown in that modal?
I would appreciate it, thanks!

11/08/2023, 8:29 PMAh, I see. We weren't handling the case where the split is 0 for some variations.
Thank you!
