On this map bhop_strafe_sepulchre you can't get past this stage there's some trigger that doesn't let you reach the second platform. I'm not sure if this is intentional and you're meant to do something weird but no one has finished this map so I guess maybe it's a bug. The map seems fun until this point so please fix when you can admins (no rush).
I'm not sure why the map creator added a trigger there, I think it's a small mistake when he was creating it. Trigger: (It's the trigger above the head, which is ruining it). The same thing happens on the last level, it's a strafe map, I tried to complete it but as you said it's not possible to finish (for me). Maybe @Arya has some good ideas? If not, guess we will need to remove it.
Went to look at it but someone added a teleport zone already, the trigger at end is intentional , "run crouch" part.
I added the teleport, but wasn't sure it was working great. Anyway, I'm happy that you can finish the map now. Thanks for letting us know! If you find more maps, please let us know.
That map is initially intended to be played on scroll settings, not auto. If you'd remove the teleport zone you added in OP's screenshot and scroll instead of holding spacebar, you should be able to pass that part without issues. Same for the triggers at the 2nd screenshot in your post Kenny. As Chris said that part is intended for run crouch, without jumping.
