Strange behavior after enabling Auto Bed Leveling

Hello,

I've recently upgraded my prusa i3 with a BLtouch auto leveling sensor. Everything works fine except it seems that the printer somehow ignores the minimum software endstop for the Z axis.
After calibrating the printer I've set #define min_software_endstops to true. When issuing G28 the printer homes all axis and leaves the Z axis at the proper position (at Z probe offset). If I issue G0 Z0 the print head moves to the correct position.
Now, If I issue G0 Z-1 or I try to move the print head from pronterface, it will happily crash into the print bed. It seems that #define min_software_endstops true doesn't do anything in this case. Is this a bug? Is there a fix?

Thanks!

if you haven't figured it out yet, in your configuration_adv.h there is a line

#define ENDSTOPS_ONLY_FOR_HOMING

uncommenting this will stop the printer from crashing.
also

#define min_software_endstops false

will allow the printer to crash
