Oh yeah the defpack thing had several problems on my end as well. Should be ready on the next release.
If robot eats a weapon in his inventory, he won't know which one you want him to eat. My only idea regarding chicken & robot active ability is to auto put a weapon in 1->6 order from the inventory to slot B based on availability.
Also, regarding the delay for the timeslow & radial menu pop-up. How long would you figure to be ideal?
