you actually could have seen the pool with no admin panel you would just need the very rare chance of your screen glitching into a certain spot when the core activates (it doesn’t glitch every time but it’s hard to get the camera to the pool)
for the one with driving off the map through the water, you can do it. you just have to be going full speed over the ramp at the drag strip, and that ends up bypassing the invisible barrier.
I May be a little late to this video but In myth #7 I’ve actually tried that like a year ago and i actually got out of the map with my car. In the water and minutes of boosting the pool of water ended and I could drive freely but my character teleported to spawn but I teleported back to my vehicle I’m pretty sure they patched it but it worked before. Thanks for taking your time and reading all of this have a good day
