Status: Fixed for the next update.
The LemCountBlink seems to ask the following:
#[Lemmings on screen] + # [Lemmings in Hatch] + #[INITIAL Cloner Skills] >= #[Save Requirement] - #[Lemmings saved]
It should be:
#[Lemmings on screen] + # [Lemmings in Hatch] + #[CURRENT Cloner Skills] >= #[Save Requirement] - #[Lemmings saved]
An example: In a level with 20 lemmings, 20 cloners and a save requirement of 40 lemmings, you have to lose 21 lemmings until the LemCountBlink activates.
Fixed for next update.
