Apparently, certain maps that use overworld vendors (see Slateport Market for an example) make use of BG palette 12 for the mart menu. If any tiles are using palette 12, they will end up looking distorted. Porytiles should support an option like -forbid-hardware-palette=12 so that the compilation algorithm is forced to keep palette 12 unused. Users can specify this option on specific maps where they intend to have an overworld vendor. For maps with no vendors, then palette 12 (or whatever the top palette is based on fieldmap settings) can be used with no issues.
