i worked on goldenrod gym for about half an hour tonight and ran into some issues
-converting a floor to anything would mangle the textures in entity fields. this happened because i got that working them merged the properties for Texture on floors and Textures on everything else except NPCs (who don't use rectangles, those are hard coded to animate it the same way across systems that won't see your map data). i was changing the entity type then asking it for its textures, and to give me a different one if its a floor, but it was already not a floor as far as my code was concerned, and would give a blank value, making it so you had no textures when it converted. then the textures property would act weird about it. should be fixed
-converting an existing entity to a step block would set entity id to StepBlock, but those are just called Step for some reason. there was some confusing because i call them stepblocks internally, step is a vb keyword so can't name a class that. anyway it changes the entityid subtag correctly now
-auto save was saving both the backup AND the map, so you had no control over when to save, ooops. fixed too
any big problems other than the decimals thing people found?
