This addon is overall really good, however I'd like to mention the one error that keeps popping up, that being that occasionally, enemies will have a stroke and stop moving or doing anything until they're killed. This seems to be an issue with attack interruption or something, as I most commonly notice this with the Cyberdemon's and Tyrant's homing laser attack, where he'll stroke if he prepares the attack but whatever he's targeting dies before he can use the move and he can't find a suitable replacement, and the Staff Hell Guard freezing up in the middle of his fireball dash. This has happened to other demons as well, mainly other bosses; I'm pretty sure this has happened to almost every single boss/mini-boss currently ported besides the Marauder, though I haven't witnessed the moment the glitch occurs besides the aforementioned Cyberdemon; usually I'm setting up an NPC vs NPC war and when I come back to it about halfway through it's already happened. I can't think of any examples of non-boss demons glitching out like this, but if I do I'll report it here. The next time any demon goes catatonic I'll post the resulting error code in the console here, because I'm pretty sure that's helpful info.
