You're using a Maketurn program which is incompatible with PHost. Programs known to work are:
- maketurn.exe from DOS Planets (can't cancel build orders, though)
- Winplan's built-in maketurn
- VPMKTRN
- PCC's built-in maketurn from PCC 1.0.3 and later
- VPA's built-in maketurn from VPA 3.60f and later
- K-Maketurn
- Stefan Reuther's Portable Maketurn
The Maketurn program must be careful not to trigger PHost's workaround for the above bug, and must send all commands in the canonical order. See Technical info on turn files for details.
