You sure? How can you know they got tired of LFS, and Scawen hitting this hard part where he has to change a lot of boring things about tyre physics may be changing business? Or if not so extreme, how can you know that they haven't started only working on LFS as a part time? Specially Scawen which from what i can see is/was the only one working full time on LFS on the last updates... Anyway, just enjoy LFS as it is. As they say here, Hope for the best, be prepared for the worst, and try to accept the outcome.
Well, don't try and act like you can "push" Scawen into developing any faster which would result in us getting them even slower because we all know your voice means sweet "f" all just like everybody else's
