I joined one map together, and there were hideouts, I've completed both, but the quest is not marked as complete completed. When I went to search the maps in the prickly Lake, I found none.
It's a bug.

I have a similar problem i keep collecting extra map pieces. It happens if there are more than one quest to prickly lake. You keep getting no pieces, or the same pieces that won't fit. You have to totally complete the first hideout. By totally i mean go to Silverton and collect the reward. Then when you go to prickly lake you will get pieces to fit. I found that out after like 3 trips to prickly lake.
Its annoying because I often park quests to give me time to reset SC and CT so those stupid wastes of quests don't end up on my board.
In the video I found two pieces on the map that didn't fit together and went home and one of the pieces fit with the one at home. After I had completed the other prickly lake hideout and gone to prickly lake again.
