I’m not sure how to reproduce this issue but in one of my decks, sims with different `desired retention` show different review counts for day 0.

I changed the DR and did a reschedule and started noticing this after that. The deck itself only has 48 review/4 learn cards. The simulator can show a much a higher number when I change DR.

I can share the deck over discord/PMs if anoyone wants to repro this.

I’m not sure whether my recent bug fixing patches has solved this problem. Could you share the affected deck with me? I will try to reproduce it when I’m available.

This happens in any deck where cards are overdue.

It is already fixed if its the same problem.
