Hey!
Its 0.11.0c.
So one of my slaves was outside the mansion gathering resources.
Then some common random event triggered for this slave.
Slave was recalled to mansion.
Yet resources still being gathered.
Only way to get rid of this bug is to dismiss/sell the slave that has triggered it.
At least that is the only workaround that I have found.
Its undesirable, because I don't want to get rid of Daisy.
