i also couldn't get quest items for the Bain & Bajin quest in the alchemist job change quest because i was too full with too many different kinds of items. at least it should've dropped on the floor, that way i still could've gotten it, but it didn't even give it at all. i can't get the 5 burnt tree because heat stove is in mine dungeon lvl 2 and even mine dungeon lvl 1 is too hard for my lvl 73 rogue. i would've changed last week and been lvl in the 80s by now...
Going around with a full inventory is handled very ungracefully by RO. Don't do it, it makes things go badly. NPC's can't direct items to the floor in the event of full inventory, and there would be serious exploits possible if they could.
Set up a buying shop ( www.irowiki.org/wiki/Buying_Store ) to get the burnt trees, lots of people have a few of them kicking around that they'd sell you.
The assassin job change is failing to give out the necklace fairly often now, and it's not clear why. You can try a buying shop or looking in vends to get one, or submit a ticket at support.warpportal.com
