HB gets stuck when bags are full

[Crazyd22]

Hey,
whenever I set my bot up to mail it gets stuck when the bags are full. It spams

Going to mail
At vendor because bag space needed. I have only 2 free.

over and over, sitting at the vendor.

I have had it working before, but it just suddenly stopped. I am using HB2, but it was also doing the same on HB1.

Any ideas?
Thanks.
