The strat gameplay system uses sequential chart encoding for current_on_base_code: 0=empty, 1=R1, 2=R2, 3=R3, 4=R1+R2, 5=R1+R3, 6=R2+R3, 7=loaded. Previously was bit-field (3=R1+R2, 4=R3) which caused mismatch with runner_advancement chart code. Fixed in calculate_on_base_code() in game_models.py (2025-02-08).
