The synchronisation of all the teleportals actually happens when you first enter Itorash. I haven't checked the 100% route in a little while, but from what I remember from the old route, it dosen't seem to help speed things up enough to be a useful detour because it would mean that you need to deafeat the Golden Chozo first, then take the elevator to Itorash up, then down, and then you could go back to collecting the rest of the items you need. What's more, it only links together the teleportals that you have alerady used at least once, so if there is any teleportals that's not already activated, it won't be linked to all the others until you find it manually.

Yeah now that you mention it, I think it may have been because of the power bomb, but it must be a really weirdly specific case, cause I was never able to reproduce it outside of runs. But just to be sure I'm gonna stop laying power bombs there XD

Hi ! I don't know if it's a known issue or not, but I found a weird crash that happens during the escape sequence. At first I thought it was just a random crash, but it has happened 4 times now and I'm still not sure why. The only thing that I know is that it always happens in that room: https://imgur.com/a/4nBz38p (the one with the red cursor in the middle) The crash had happened before 1.0.2 got released, so I don't think the crash is new. I tried to replicate it to find why it crashed, but to no avail, and the only times it happened were during runs when I least expected it (I lost 4 good PB to that crash) Anyone else got that issue ? And if so, do you know why it happens and how to avoid it ?
