I finished this huge building and when i press the build button the game tell me that " there are red blocks " and I cant build i would like to solve this problem before I use the ib command.
easy thing you can try:
if you dont SEE any red blocks anywhere, save the template, then delete the building, then put the template down and try buildign it again. often that will fix it.
if you DO see red blocks anywhere (for instance, too deep in the floor or something, delete those first ofc.) a picture of your build might help
i mean assume you dont have a building there yet, look in your saved buildign temaplates, and put this thing down again (after you make sure this one is saved, and hit the trashcan icon to remove this thing so there is an open spot there)
ps. i hope you are using my MRF mod because holy -beep- you have a lot of farming going on in the back there… (you need like …3 of those fields to feed 20 lings. and you have 18 )
