So,i tried to make a big map on 2 floors( has 3d floors,yes) and some of the sectors with floors and ceilings cause HOMs on the world.When i try to remove and remove one HOM another HOM is on the run.

this is the where i have uploaded my map.It is Doom 2 in UDMF format for GZDOOM.I made very small sectors that occupy very small place on the map,so do not confuse if you do not see them and think there are no sectors.Just zoom.I do not know where the other HOM s come from.Can somebody help me remove those hell?
