Bonus 4 is pretty stupid anyway, I used a flat duration for the trigger instead of making it so it would only apply the condition while you were in the volume. I think what people were doing was using /setstart on bonus 2 and then going to bonus 4 to get the mini state and then skip the jump. Anywhere else it'd probably be only slightly quicker than doing the jump normally I think. When I last talked to Rob about it he sent me the stripper file that showed that all of the stuff has been removed for bonus 4 anyway, so it should not be possible to do anything with it on Tempus currently.
For the record all of the orange platforms are secrets and not bonuses. They're on 3, 9 and 15 if you want to go back and add them in though. The only thing that should need to be changed is removing the buff trigger on the pumpkin skip. There didn't really seem to be any issue with adding the secrets in as bonuses on benroads2 so I would imagine it won't really be an issue.
