Due to certain bugs discovered in V1.25, I've put the link for V1.24 back in the original post. (The link for V1.25 is also there but I recommend treating it as an experimental again.)
I have to say - I am very annoyed that after this being available as an experimental for over a month, no one found either of two major bugs that have now come up, and yet they were uncovered within two days of stable release. This leads me to believe that what I interpreted as "no one is having problems with this experimental" was actually "no one has bothered to test this experimental".
Please keep in mind that I am spending less and less time on Lemmings these days because I have other projects I'm trying to work on too. While I do some testing, there's only so much I can catch myself, and this is why experimentals exist - so that the community can assist with testing and help find these bugs. If the community is not willing to help with such testing, then the only alternative is that I stop introducing new features unless they're so simple that they very likely cannot have bugs - and certianly, things like new skills and new object types are out of the question.
I'm not putting any promises on when I'll fix this - if it wasn't important enough to the community for anyone to test it, it isn't important enough for me to make a huge rush to fix either. However, I do strongly advise going back to V1.24 unless you are specifically using V1.25 for the purpose of bug testing.
