Back with replays of some resolved levels.
Levels I needed to resolve:
Armani's
"Childhood Dreams" R1V3 and
"The Good, The Bad, and The Weird" R3V7 - I had the intended solution for the former already, but unfortunately the update broke my replay, so I had to do it again.
Your R3 needs fixing again, as I totally backrouted it
Crane's
"Immortal" R3V12 - I think this might be a backroute as well
Just slightly harder, although I must say that was super close before the regular lemming got infected
It really looked like he should be, though.
I still need to resolve your R1. It has me stumped. I will try again later.

"Come Home Lemmings" R1V5 - It's definitely more challenging now, though I admit I was very annoyed at the tight timing needed for the end part. Kind of doesn't help that I was resolving contest levels on my birthday
Not your fault at all. I'm guessing RR changes would had made my life easier.
Niesch's
"Take A Hike" R1V2 - Apparently even a slight shift in the terrain was enough to break my replay. I think this time my solution is only slightly different than the one I found in the first version. In any case, not that much harder than before.
Shmolem's
"Climb the Water Tower" R1V2 - I attached two replays. First one I save everyone, while the second one it is possible to completely ignore one entrance. In any case, both should be backroutes, as you mentioned that going underneath is not intended
Flopsy's
"Let's play some games" R2V3 - Slightly harder now. Maybe still a backroute, though?
