D: Try it without console commands as Mu to see if you TRULY do need Co-op

C: Use the ghost command to skip the whole thing

Co-op is never required, only use it to...
A: Piss off (Not literally you pecking jerk) Mod Creators...
B: Break their map (You can do that tho :hueh:)

Yeah that was 100% issue, that I could only test once it was in the workshop and since it auto publishes you probably got that build. I did fix the button syncs in the last update (hopefully) but if you run into any issues I would suggest the kirby hat to cheese the map. I had that experience with the checkpoints but that was only during the final, which I believe was caused by everything being dweller material. Let me know if it happens again.

did this with a friend and we had alot of trouble syncing the buttons together, we had to go press each button ourselves which is hard because some parts are meant for mu and vice versa, and the checkpoints were a bit wonky as well, going as far as 2 checkpoints back when we fell sometimes, but then again we downloaded this and then the mod disappeared or went private cause the link didnt work anymore when i tried to send it to other friends, so i may be reviewing a older version
