Hello, just recently started using the vault save and every time i restart my run after the first run the timer on livesplit goes back to 0.00 instead of 53.01, how to fix please :(

Edit: to clear up confusion, I have to basically go in and hit edit splits and change the start time to 53.01 after every run when I want to restart or else I will start at 0 and I dont want to have to change the start time after every run and I just want to start a run.

ok so i started speedrunning portal about a week ago and ive been doing inbounds but I got on this morning to do some runs and once i reach escape_01 im stuck in the room because the pistons that fall down after you go through are already down and I cant do anything. I dont want to have to redownload the game but could I redownload the map and put it in the maps folder somehow? or will that mess something up?
