There are several uint8 values in 'Source/world/map.h'. Two important ones appear to be 'base_height' and 'clearance_height'. I tried changing 'clearance_height' to uint16, but it's size is protected by several 'assert_struct_size' statements. Commenting out these statements with the modified integer size just results in a crash upon boot. The exact size of these data types is very important, it seems.
