turbing controller in f3 regarded as a fluid and "minecraft:empty". turbine controller calls itself wrong block

nvm this was me being stupid and it being on a corner which isn't a thing you can do sorry. it works fine if it's part of the wall
also for some reason i couldn't read the f3 properly and assumed it would either say fluid or block. not both. the target block works fine
