So hey, I'm not sure if you wanted the 1st and 5th floors (iz_dun00 and iz_dun04) or if you meant iz_dun01 and iz_dun05, so I included copies of all of them just in case. If you want, download here; If you need help adding the map, refer to this guide. If after reading, you still have questions, join the Discord chat an I'd be happy to walk you through the process.
