What bot are you trying to erase? Give me the name, and I will take a look at it. Do you want me to erase its entire memory?
Note, when you erase a bot's memory it will rebootstrap, so its memory will not be left a 0, but it should not go up, that would mean the erase failed, possibly due to database locks. The error above is normal and not the issue (it is just checking that an index was created).
