Started messing around on Switch... All the bugs seem to work the same. Also the skeletons have failed to spawn EVERY time, even on grey knight without setting up any button glitches. Honestly seems like the ideal platform?

"i've never seen the gunner not spawn, and i've reset right after hitting the button. is there something more to it?"

I'm not sure. When I reset after hitting the button, I used the squire teleporters to go back to C8 to set up the other buttons. I'm not sure if this is why it didn't respawn?

All three buttons (the one for Checkpoint 7 and both for Checkpoint 8 ) will remain pressed after you restart, but will reset if you die anywhere from Checkpoint 6 onward. Dying prior to C6 is "safe" because the zone with the buttons is unloaded.
