You should examine the beginning of the input file, where the program prints
out the weight change information: be sure it seems to do what you want.
I don't see anything obviously wrong with the input, but I'm probably missing
something. But try some short(!) test cases to make sure annealing is doing
what you want -- something like 1,000 to 10,000 times shorter than what you
showed here.

Note that even without cooling, you have essentially zero restraint
violations. I have no idea whether this means that your structures are really
good, or that your restraints are too weak, but it is something to look into.
