well the items we trying to put in multi-sell uses ids from 10000 to 90041 and we got some custom farming coins as well which ones have ids from 100100 to 100130, and no not all items have same problem from the ids which i just wrote here all items don't show armor - weapon - coin icons only the names of the items also only one weapon set is working fine when you put them in multi-sell and one or two armor sets has almost same problem as here: http://www.maxcheaters.com/topic/189018-critical-error/ but we don't need to click on item to get the error, it is enough just open the tab where the items are and you get kicked out from game with the error, i was trying to contact the person who had this problem and hes fixed it, but i have not received any reply from him (there is only 2 options with which ones we do not have any problems with all the items 1. spawning them in inventory 2. putting them in default l2 c6 shop to be sold for adenas) only these 2 options are alright with items, so i'm not sure if it is with the patch like ganjaradio sayd or it is something more to do with java configurations that multi-sell would work alright
