Answers below:
Server: Zikiel - see the Original Post
NPC - Owenstein and Hilary - see the topic of this post
Question 3: Who many daily exchanges did you have left when first talking to the NPC? - 5 see the original post
Question 4: When was the last time you've exchanged on that NPC prior to the server maintenance? (Please use CEST for EU servers, and Pacific Time zone for US servers) - Hilary never (I didn't use it in previous event) Owenstein not sure it was probably 16th of October. 1 p.m. CEST (certainly not the last day of the event)
Question 5: When did you talk to the NPC for the last time prior to the server maintenance, even if you did not exchange items? - Hilary only first day of previous event, 12th of October, not sure about hour. Owenstein 16th of October 1 p.m. CEST approx (also the last exchange)
Now...can you answer the important question how many exchanges is correct? Why some people can exchange 10 times after maintenance and some only 5?
Thank you.
