Hatch preview shows correct hatch but creating the hatch doesn't work

I am trying to hatch a floor plan with blocks, such as window & door blocks. The hatch preview shows a perfect hatch, which stays inside the boundaries of the room. However, when I click to create the hatch it suddenly creates a hatch that goes outside of the borders of the closed boundary. 

 

It looks like the problems occur through the window and door blocks particularly, but I cannot tell exactly whats wrong. This floor plan has been copies and mirrored. After searching the forums for days, i have tried all of the suggested commands such as setting MIRRHATCH from 0 to 1, using REGEN before hatching, using less dense hatches and stetting other hatch command variables from 0 to 1 or 1 to 0, but nothing works.

 

I deleted everything off of my file except the one room i wanted to hatch, purged all unused layers, to see if my file was too big and was causing issues. I also tried using current as well as specified hatch origin. Tried using bhatch instead of hatch. No luck still.

 

My hatch settings have island detection checked, and island display style on "outer".

 

I'm lost as to why the preview shows it correctly but then when creating the hatch it blends outside boundary, says too many objects to hatch, or even no boundary found sometimes. 

 

Any help would be extremely appreciated.

Attach a drawing (or a slimmed down version of it) for specific help.

As a general rule, if you want to hatch something correctly the first time, create a proper, closed polyline to contain the hatch, and hatch that entity. Allowing AutoCAD to find the boundary itself, by flooding can be a time-wasting effort.
