How to reproduce

Slice the attached model with "Tree Hybrid" supports enabled, default 0.16 profile, PLA, and two wall loops set. Set the print order to outer/inner/infill (IMPORTANT!).

Actual results

The treelike supports have a massive overextrusion during the base bottom shells are printed (see attached picture) while the rest of the model is doing fine. Also only the first few solid layers of the supports are affected (bottom shells). The problem seems to be, if two wall loops are enabled, the solid infill does not take into account the inner wall loop and prints right above it causing filament to build up.

Expected results

The first few solid layers of the supports are printed taking into account the second inner wall loop, without causing over extrusion.
