What is happening:
I discovered that I can't interact with any pony who has been invited to the rehearsal anymore.
I can't talk to them neither can I progress in other open quests that involves them.
As I have another issue with this quest (http://phabricator.legendsofequestria.com/T2031), I don't want to hand it in.
So it might be possible that the interaction with the ponies in question unlocks after completing "Rehearsal Roundup".
For example, I can't talk to Silicon for the quest "It Makes Sense To Me" even though him even having a quest exclamation mark floating above him.
Pressing talk just does nothing.
What should be happening:
You should still be able to talk to ponies and be able to progress in other quests while doing "Rehearsal Roundup".
Just as other quests can be done simultaneously and just as you can talk again to ponies after doing quest stuff.
Steps to reproduce the issue:
Ad normal dialogue:
• Accept the quest "Rehearsal Roundup" given by Pitch Perfect and Choral Codex • Give to such a pony a Song Sheet Music • Try to talk to them as usual, but nothing will happen
Ad simultaneous quests:
• Accept the quest "Rehearsal Roundup" given by Pitch Perfect and Choral Codex • Accept other quests that involve the ponies which are supposed to receive an invitation (for example "It Makes Sense To Me") • Give to such a pony a Song Sheet Music (would be Silicon in the given example) • Try to talk to them as usual, but nothing will happen • Other quests are deadlocked
