[1.31] Turtles don't work outside of a certain radius from origin

I have a base very far from the origin (-52700, 1500) and turtles wouldn't work. I looked into the problem a bit and found that you can draw a square along the +/-32767 (signed 16-bit?) coordinate line and outside of this square turtles do not function.

Maybe something to do with chunks? Use a program like MCEdit and change where the spawn is on the map.

More likely the programmming uses signed 16 bit numbers :(/>/>.

I though that lua uses 64 bit floating point numbers (48 bit for real, 16 for floating point) arent it ?

This is nothing to do with Lua though. This is Java side.
