NPC merchant stuck after empty autosell

If you trigger an empty autosell (by using the console or a macro in the example bellow) the sequence will fail and openkore won't be able to talk to npc merchants again.

Issue noted in xKore 3, unsure if it happens in Poseidon or xKore 0-1-2

Needs further testing.

Reproduce an empty autosell using the console or the macro example in xKore 3, starting from the logged auto-sell sequence and the missing sell result. Compare behavior with Poseidon and xKore 0-1-2 if possible; done means the empty sequence completes without leaving OpenKore unable to talk to NPC merchants.
