The stp_w part was commented later but the get_next_transition part causes this. The changed behavior starts at 0xfea38.

Same apply for pcjr - refuse to run dos21 after 0.181!
Warning: The problem appears to be global!

Yup, commenting it out does fix the pcjr too so I've done that to solve it until it can be properly investigated.
