I JUST WANT TO REPORT A BUG AND ASK FOR A FIX OR SOLUTION IN ANGRY BIRDS EPIC: This happened to me twice so far. When I got to these two workshops, the one on Winter Wonderland and the one just after the Islands in the Sky level, after opening the buy interface, I found out that 2 blueprints (per workshop) are already sold out while I just got there and I didn’t buy anything, I still can buy the non-sold-out one though. I just really want those items. Apparently I’m not alone. (https://www.angrybirdsnest.com/forums/reply/174272)
