While this happened with the armor stand screen, it seems like the error actually originated in some vanilla code. The fact that it's a ConcurrentModificationException on an internal class tells me there may be some other mod causing this.

There shouldn't be any opportunity for this particular exception to get thrown in Minecraft. My best guess is there's a performance mod trying to do some kind of multithreading that caused this.
