Forum:Mountains of Zel - big error!

alright, so i go to the mountains of zel event, pick the 30 pointer, and everything starts to go as normal. Suddenly, after a battle, the chests show up, but i cant open them! This isnt a noob issue of me not realizing the battle wasnt over - there was nothing left to attack, no activity going on, just the chests sitting there with no way to open them! This has happened almost every time this weekend, never happened before, and its wasting my points (the open option left is to back out, causing me to lose my progress). Is this somehow my fault? Is it a new error? Has anyone else had the problem?
