I ask you please don't reply in before you have read the bug, the post, and be sure that what you say is not stupid.
Here we are talking about the bug that blocks the siege when an ally enters. Whoever wants to take the siege, the producers of the game decide that, but if it LOCKS when they enter the siege and you have to exit and re-enter to make it go on, this is a bug. Please read unrelated things before replying.
