You can see this when you loot, you spam interact with target obnoxiously for a group quest item or a item with a bop prompt and you get the 'i cannot loot that' or 'object busy' errors. Then try and cast a spell (so for me 'all thunderstorm') and it will occur a considerable delay from when I typed it (and might not actually occur if i am hyper obnoxious with the spamming)

My guess is that there is a pathing compute function that has this lag associated with it.
