An issue to be aware of...
If your pack gets full while getting artifact drops, they queue up, to be delivered to you once you have space in your pack.
Problem can arise when you die and resurrect. That is, if you resurrect when pack was full, you'll start getting the queued up drops delieverd to you. That fills your inventory up, often times before you get to your corpse. So looting your corpse may not fully succeed -- when double clicking your corpse -- depending on how many items etc went to corpse.
At least for EC users, you can apply this change, so you can act sooner in this situation:
There is/was a variation on this, where if your pack was full, and you get "stripped" naked/etc (certain mobs that use peacemaking/etc), you can over-flow a full backpack.
