Just like that, another update in quick succession. Looks like the backroute war continues. I even declared the War rank backroute free months ago after I had resolved a few versions of 4 32, but josh still ends up backrouting some of the levels in the rank. As a result, my replays for 4 20 and 4 39 still work, while they broke for 4 14 and 4 35, although the latter is more to stop the waiting around game since with the numerous amount of pickups in the level it's pretty much backroute free, or so I believe. In any case, I've already fixed my replays for those two, so not a problem.
edit: for 4 35, I managed to beat it in 8:17, in other words, with 2 minutes and 54 seconds left on the timer. In the process, I have a walker leftover. That probably won't change the timer you set for the level though, as you don't want it to be too tight.
