If player->simulation, shiprepair(), planerepair(), landrepair() must use the bp map, and must not change game state. Copy the sector to a scratch buffer, update it from the bp map, work on the sector normally, then write back to the bp map. This is simpler and safer. Since get_materials() loses its connection to the bp map, move its declaration out of budg.h. While there, drop an ancient debugging logerror() from landrepair().
