Hi everyone, I’m new around here.  If I do something wrong, I’d much rather be politely corrected than flamed   
I’ve just started playing Reborn, and I just finished the part where you storm the factory (Team Meteor’s hideout). 
I wanted to know the Pokémon in Julia’s team before facing her, so I looked around for a walkthrough and found sparsyle-0’s one (http://www.pokemonreborn.com/forum/index.php?showtopic=13417). 
Looking through it, I saw that I’ve missed a lot of stuff, like event Pokémon and items, including the Ability Capsule. 
But when I returned to the factory to get it, I found that the entrance was blocked by rubble, sealing me off from the barrel containing the Ability Capsule. 
So, what I want to know is: 
1. Does the rubble blocking the barrel disappear later on in the game, or is it there for good? 
2. If I want that Ability Capsule, will I have to restart my game? 
3. Does it really matter that I missed out on it, or are there an abundance of Ability Capsules hidden elsewhere in the game?
