In Pip-Boy > data > workshops, sometimes it shows the wrong number of resources in a settlement, and/or indicates a problem (with an exclamation mark) when there is no problem. If a settlement has 10 beds or 10 settlers, it may show only 1 or 2, giving you momentary anxiety; then when you go to that settlement, you notice nothing has been changed and the Pip-Boy shows the correct info again. The map screen may also show the wrong number of settlers -- until you go to that settlement and it shows the correct number again. This has happened so many times that I have lost count. It has happened both before and after the latest beta patch. Right now, I just resort to visiting every settlement regularly to check on them, but I don't know if I can keep this up if my settlements grow in number.
