That is a z-warp. If you check out my climb IL it is being used there . Hel Dlc out of bounds use it as well. Same goes for new category in category extensions.
Closes thing to no NG+ ILs you can get is in category extensions - samurai% ILs.
I feel like no NG+ ILs would be way to big of a hassle for moderators and runners since you would most likely need to show upgrades at the start of the run every single time, to prove that you don't have anything extra unlocked.
- you would need to close the game to reset your progression all the time ( i know that unlocker would make it better but it still dsnt sound like fun time )
As Ekorn said : for demo we use In game time. for full game runs we prefer if you did have auto splitter unless you are on console or if there is good reason to not use it on PC. Since re-timing runs takes a lot of time.
You should ask for help on Discord for downpatching
never mind- you can get full game splits in the resources on src as well
you can download auto splitter in Discord in resources it hasn't been uploaded anywhere i htink
