Rejected NPC completely disapear

Bug Name:

NPC completely disapear​

Bug Description:

After being logged a few hours, NPC's disapear (all of them) and I also lose the ability of talking in the chat. My character is in game and I can walk freely but I'm just cut off from the rest of the server. This happened in town and grinding. ESC to see the menu also stops working.

The only fix is to force close the client and run it again.​

How to reproduce/proof:

​

 

It happen if client disconnect from server. Not related to NPCs or other, u just not send and not recieve packet from server. If u will find way how to easy repeat it - reate another ticket plz. Thanks.
