I'm having this issue as well, except in my case there's a time limit on my drop pods.

I'm running Rimworld of Magic, which includes a teleportation spell that spawns temporary drop pods (the cooldown is really long) and there's a time limit to fill the pod and send it or it explodes. :( The spells work like psycasts, except they consume mana instead of psychic energy, and have quite a cooldown. I've been trying to use them to send back stuff at caravan events that I can't haul back, or to get back more quickly and safely, but my pawns keep taking all day to load the pods :(

yeah i have this issue too. idk why. not only drop pods, also when hauling to vehicle caravan, srts, etc
