Nope... Is Ingar willing to fix everything in Tremor? If yes:
Z-fighting in vent room at alien front.
Missing surfaces at bottom edge of front and back ladder holes.
2 instances of overlapping brush in basement near ceiling at junctions (easy to see with higher gamma, as they are z-fighting with a black surface)
Box room boxes with misaligned tex:
top edge of boxes where a goon can be safe from non jets
at back right corner, at pile of crates is 1 separate crate, top and front faces
top of that same pile front/top/back faces of the three boxes
the largest pile (near entrance to h base) lowest boxes
Above alien base back entrance there is a gap just below the ledge
Just left of the ledge there is a tiny missing surface (easy to see with /r_clear 1)
The boxes in alien base are hovering
Misaligned brushes
From human front turn around at first junction and at top left corner
from there go left all the way to the wall, turn around, and at top left corner.
1 of the pipes at human base plants is missing a cap
These are what I can remember/find atm.
Edited and added some, also checked: these are all in tremor-gpp
