If you throw vehicle of the cliff and try to talk to characte while it's falling, you will be teleported on vehicle and character message will pop every time you press F and you can teleport on vehicle again (may cause jumping of the bounds).
Fun fact: after I spoke to the Riceman everytime I press F the dialogue with him appears. But that's fine, because if you press F while bug happens and you're jumping you will move in a direction of your jump without falling, so you can "fly" anywhere you want.
And you probably know about the mission showing you that you need 100.000 points at first, but you actually need only 10.000... and about 6 FPS at Warehouse.
Ok, I'll just add a couple more: If you "die" when mission timer at 0:00 this dialogue will stuck forever and reapeats after pressing F. You still can move freely. After next "death" it stops... and repeats after starting another conversation. It even allows to move in pause menu.
