While fixing United levels a bug caught my eye.
I had a level with 8 cloners and a save requirement of 74 out of 70 lemmings.
A backroute forces me to place these 8 cloners as pick-up skills. So I placed two 4 pick up stacks and set the cloner ammount to 0.
While testing if the replay still works I noticed NL saying that the save requirement is now 72 out of 70. But the editor and the level's text file still stated 74.
So I changed the cloner ammount:
0 cloner --> 72 out of 70
1 cloner --> 71 out of 70
2 cloners --> 72 out of 70
3 cloners --> 73 out of 70
>= 4 cloners --> 74 out of 70 (as it should be)
Now I split the 2x4 pick ups into single ones to see if that causes problems: We've got a hit!
With 8 single ones the save requirement is 74 again.
So there is something between stacked cloner pick-ups and changing the overall cloner ammount that meddles with the save requirment.
I attached the level with the 2x4 pick up variant as an example.
