Jungle Item bug

As thresh i thought it would b a funny cheese item to get the devourer stalker blade for the AS and magic dmg on hit. However, i was pretty sure you cant purchase jungle items without smite. But, i checked the shop and it let me buy the items, so i tried to buy the base item and i didn't notice at first but i lost the gold and nothing was in my inventory, so i saved up enough to buy the full item and try again, yet again the gold disappeared and no item. Kinda an odd bug and maybe a bit situational, but still, i was pretty sure you cant buy jungle items, yet it said i could, then duped me for my gold. the link is the match, there isn't much proof aside from if you look, i buy a dagger building up to the jungle item, yet in my end build it isn't there, and if u check player build, i never sold it, it just disappears, just thought someone should know, i checked boards really quick and didn't see it so figured id point it out
