Another huge problem came to my mind with RR shortage under 50:
How about we break near to 100% of all replays that don't use one of the then remaining RR'S as the start parameter? As most custom start RR's are even numbers like 10, 20, 15, 30,....,60, 80, 90... not 99, 87, 75, 63, 51, 39, 27, 15, 3 as with the 1 to 9 method
So we nearly break all replays with custom RR's other than 1, 99 and the few odd remaining values......what else?
Most level creators set the start RR in a level that doesn't really need the RR to sth arbitrary like let's say 40 for an example. Not only does the replay depend on this as every Lemming other than the first will be at another place after this change, no even the level itself could be built unintentionally to work with start RR 40 then. Of course it could to 99% be altered to work with a new start RR,
but it has still to be altered.
So we break I say way over half the replays, break a ton of levels ("most" [not all] of them fixable) .... only to save a few RR steps...... yeah, let's not do that Yes, the new version will still break ~ 25% of the replays, but in that cases for huge benefits as glitch-free gameplay (hinting at the builder glitch) and consistancy (hinting at wrong facing OWW's).
With RR 50 we still throw out half of the RR values and by dividing the old RR's by 2 we get 100% backward compability .... let's do that instead, shall we?
