Im using bluestreak to export, I exported it 3 damn times. The map itself is definitly sealed..

then it is the fact that you are using tools that are not best for halo ce.
Use max8 and blitz.

Same tools worked before without any issues

You're in editable poly, if you are using border select? Convert to editable mesh and weld.
If not, you should import the wrl file from the Halo CE directory to see exactly where tool thinks errors are.
