First of all, you don’t need to change motherboards to run 3.10. What the note means is that IF ever you need to replace your hobbit motherboard you need to be running at least 3.0 to use that new board. Update yours to 3.10 software.

The beast mechs all have scoring switches behind the figurines and they may need adjustment. Test them in either beast mech test or matrixed switch test and see if they are scoring properly. They might need adjustment (adjust the rear blade only not the front blade - leave the front blade alone). If the switches are too close, the vibration of raising can cause the beast hit switch to score thus it will drop immediately. If the hit switches don’t work at all, check to see if the wires have gotten cut or pinched underneath (that’s a common hobbit thing).

Kickback (windlance) is probably the rollover switch in its lane needing an adjustment to make it read correctly as the ball passes over it. Tests - switch tests- matrixed switch test then roll the pinball over it slowly and then more rapidly and see if it is in need of a little adjustment.

The DWARF bank has a little plastic shelf that holds the target in the up position - that could be broken or cracked OR there are adjustment screws (long thin 1 size philips) at the bottom of each of the 11 drop targets - if they have spun too low or fallen out from repeated drop target pounding, the targets will sit too low in the hole (they will not be flush with the playfield surface when in the down position). This means they won’t come up and catch on the shelf properly when the game lifts them up. Look under there, adjust and or find and install the white nylon adjustment screws if they’ve fallen into the cabinet and spin them up to their proper spots so that the F and all the other targets are flush with the playfield wood when in the down position.
