I have an issue with the 4-Sat contract. The "solver" gets stuck and tries to order my comsats as 1-2-4-3. This of course isn't an issue with only three, because all three are always connected to the other two, but with 4, order matters. edit: It's probably because the KSP contract constraint solver doesn't do backtracking. edit2: Basically, I actually do want Comsat III to unify with my "Comsat Earth" satellite, but it seems to have already unified with Comsat IV. edit3: anyway I backed up by persistence file if you want it; but now i auto-accepted the contract using debug
