I haven’t had crab pots on land, but haven’t been able to pick them up in 1.6 through usual methods. Here’s a workaround though:
I use tap-to-move usually, but have had to switch to joystick & buttons to pick up crab pots in 1.6 — and sometimes it takes multiple button clicks. Didn’t have this issue in 1.5.
In 1.5, I had to do this switch for a few other things — access to Lewis’s gold statue and paying for Willie’s boat, in particular.
