Off limits is now working like a charm. Firmware update from worx fixed the issue. (Firmware can be set to be updated automatically if the landroid is connected to Wifi. Would have saved me some trouble if that option was enabled by default)
Now that the off-limits is working, the getting stuck issue isn't as prevalent either, since the mower isn't going into the bumpy area i tried to close off with the off-limits.
Despite the frustrating start-up issues, now that the off limits is fixed, mower is working great. If I were to buy a mower again, the landroid would still be my choice. It seems to me that many robot mowers are very similar in performance, and the off limits and anti-collision system is what differentiates this from other mowers for me, very nifty add-ons.
