Still happening here too (assuming a non-bugged inventory, since a new character is also affected).
Current inventory: 97.50 / 195.0
Current capacity: 148.00 / 750.00
Items in inventory are Samadin\'s standard spare gear and stuff picked up while sweeping the dungeon, partly from loot, partly cleaning up whatever some litterers left behind).
Killed 1 Clacker, loot: 1 Leg, 1 Meat.
Trying to loot => You looted a Clacker Leg, but can\'t hold anymore; You looted a Clacker Meat, but can\'t hold anymore. The two items get dropped onto the floor.
All stats displayed as 100% (I waited for a few minutes, while writing this).
Trying to pick them up either via UI or via /target and /pickup results in You can\'t carry anymore Clacker leg, etc.
Casted one Life Infusion (remember, the character\'s health had been displayed as 100%, and I waited for approximately 200 seconds, which should have brought it up to 100% no matter what, so the spell should\'ve been a nop).
Result => Items can now be picked up, and killing the Clacker again lets one loot whatever it has. Steuben was right on the first count...
Edit: Please feel free to log into the character / duplicate its data into a new one (just /tell me beforehand in-game so I can log off).
Edit 2: Killing the next clacker spawned in the very same spot results in the no space left warning. Health still at 100%. Life infusion => can pick up.
