i believe this is the problem. there’s too many things happening. it’s like a run-on sentence, you have to end it sooner.
try this instead:
&EXPL walks to spot 0.947 90 156 in 2 AND EXPL does it while walk_neutral_loop_rear
&MCF walks to spot 0.902 218 187 in 2 AND MCF does it while walk_neutral_rear
@EXPL faces left
@MCF faces right
