Just attempted that level few days without hope and i have to go look completion video. I see a lot version differences.
Here is completion solution by Flopsy, but this version seems give some major version differences. Like starting release rate is 1. My version start 50 releaserate, that make right side completion impossible. Too many will die.
About left side. Here is completion solution by Flopsy. Thats look lemmings will stop bashing when it bash left side corner. About my version, lemmings will run out and all were die
If you take miner way one round earlier, too many lemmings will drop the water.
Here is Flopsy completion (just start watch this video point 10:45.

Here is my few pictures. And yeah its requires 4 builder at end so i cannot turn/cancel that basher with builder.
So that Flopsy completion solution cannot work. Seriosly i cannot find nothing strategy completed that level with those skills.
Flopsy's video is from a very old version of NeoLemmix. RR1 on that version is the same as RR50 on newer versions. Many people have solved it on the current version of NL, and there is a collection of solution replays which can be downloaded in the Lemmings Plus release topic which would prove the level is possible.
With that being said,
Spoiler
The right-side solution is not possible, and has never been possible on any version of this level.
Thanks. I finally solved it yesterday. I just totally overlooked it little bit wrong before. Its not even hard level compared most Psycho mode levels.
BTW i have my own first Neolemmix pack in progress. Its will contain 120 maybe 150 unique orginal lemmings levels you never are played.
1-LOL mode 30 levels (are maded succesfully)
2-YOLO mode 23/30 (are maded)
3-OMG mode 2/30 (are maded)
4-WTF mode (not are started that yet.
5-??? mode? Let see did we need 5 difficulty??
At this point my pack is pretty easy, but still a lot harder than licensed lemmings games. Its migth some fun time. I´ll post whole pack when i am ready. I´ll completed every levels before posting it.
