Distracto

I have a problem with tree supports. The support do not make contact with the model in all parts of the print, thus causing the model to disconnect from the support. I tried increasing the support bottom density from 10% to 40% (still have to test it out) and i also selected Z ovverides X/y and set a Z distance of 0.2 and top distance of 0.2. Although the support seem to improved when i see the slice preview, there still is a visible gap. any ideas? This is a 27 hour print which i already tried 3 times, but i just noticed what the actual issue is.
