It has been 8 hours since it became possible to complete this quest because we got 3 missions on Tuesday; 2 on Wednesday-Saturday (total is 8). So if you tried you should have already completed 10 missions. When I finished I went to talk to Reda but there is no dialogue option. There is a quest marker on him though. This will be bad in a long run because you can only buy items with opal from Reda, quests can be asked from other children.
Have heard it to be a problem caused by Ubisoft server issues but don't know for sure. Also don't know what to do if that is true.

Almost all Jorvik smaller chests contain 1 fabric.

Finally can talk to him again, for atleast once so I got my quest done. He told the same story again after the fight with Dag and was accessible after that.

How to get to the chest in Jorvik between Coppergate Market and Trade Depot (should be underground)? All I have figured out is that it is visible inside Eboracum Sewers but there is no way in from the sewers; visible spot is on the side where the Needle escapes from; from what you can see there, it should have a way in from the ground or atleast a light shines in there but when on the ground there are nearby only inaccessible houses and regular ground.

@alphamachina I'm at power level 260, of course I have it xd. Been using torch quite a lot but lost only 1 weapon. Think it has to do with using same type of weapons.

Lost two-handed sword Doppelganger. Was using 2 two-handed swords. Jomsviking is still able to equip it. Playing on PC.

Happened to me too, thought it to be a problem with Ubisoft server connection or mission "Viking for hire" though in my case I had just finished the 10 missions given by him and can't have the final talk. Have tried many times: fast travel, completed other missions, restarted the game, meditated. Also listened to the story he tells children. Playing on PC.

Also lost the greatsword called Doppelganger, been a few days but have not found help or a solution. In my case the jomsviking can still get the item. Playing on PC. Maybe important but I was using 2 greatswords.

Also to clarify the weapons name is Doppelhander and my Jomsviking can still equip it, only missing from my inventory. Luckily I got the Moonlight out of nowhere but still scared to spend resources to upgrade gear.

Lost a two-handed sword that I bought from a trader some time ago. It is gone from my inventory. It happened right after the Razing Earnningstone quest that you do with Galinn.
