Try using Partial Moment releases instead of full moment releases. You would need to modify the input file by changing all releases from MZ to MPZ 0.99, i.e:

2307 2309 2311 2316 TO 2335 2412 TO 2415 2420 2421 2423 2425 TO 2427 2432 -

2433 TO 2437 2440 2441 END MZ

change to

2307 2309 2311 2316 TO 2335 2412 TO 2415 2420 2421 2423 2425 TO 2427 2432 -

2433 TO 2437 2440 2441 END MPZ 0.99
