I've had Mr Handy out for a little over 4 days and he hasn't collected any more caps. I noticed he wasn't earlier and wanted to see if something might change... Negative. He also stopped logging anything in.

Did you mess around with your device's date and time-settings?

As I read 5000 caps was an intended limit.

I think I did a Pay To Win dorkfest as I wanted one Handy per production level and now my vault is churning out caps like there is no tomorrow... Seriously.... I had nearly 500k caps early this morning. I upgraded all my rooms to max and all though an accidental bug.

Not going to say what the bug is until I fully document it and send it to Bethesda but lets say I can make around 100k in about 5 hours.
