I noteiced that in NeoLemmix 12.02.00 (the current version from neolemmix.com), talismans that depend on skill counts unlock even if you did not meet the requirements. Here are 2 examples from Lemmings Plus I:
- Wimpy 25: I did the standard solution with 6 builders and still got the talisman for "Complete with max 3 builders".
- Wimpy 30: I saved 25 but did use floaters and still got the talisman for "Save 25 with no floaters".
If I delete the talismans from userdata.nxsv and then run the replays, the talismans get unlocked again, so the attached replays can be used to reproduce the bug.
[Edit:] I re-checked for Wimpy 30: If I save less than 25 then the talisman is not unlocked, so this is indeed a problem with calculating the number of used skills. Other requirements semm to work.
