Endless Throne Room Solo Easy 5 Star Guide
The heroes seem bugged out and don't come out of one of the gates after a certain amount of waves, but it does not affect the game very much since they are easy to kill. I did another 3-4 runs similar to this, including one with another person. In all of those runs the same thing happened, except in one run all the heroes came out at once after a while, and by the time they did there were about 15 of them. They were still easy to kill, but yeah they are bugged out a bit.
