It seems that the bot ran fine today
But it didn't take into account that we are credited every day for all posts we made up to that moment. So the bot missed one such counting, and it looks like that we will be a bit underpaid this time. Posts are counted correctly but one entry is missing which leads to incorrect (lower) total amount due (unless that NaN entry is replaced with a valid count)
I think we can live with that. After all it's not the bot's fault so.
