Is your strategy against raids (especially sappers) retreating to the secondary wall and waiting for them? Id imagine a lot of collateral damage that way, or do you just send that pack of panteras and they slaughter everyone?
On windows saves shoud be at
%USERPROFILE% \AppData\LocalLow\Ludeon Studios\RimWorld\ %USERPROFILE% \AppData\LocalLow\Ludeon Studios\RimWorld by Ludeon Studios\Saves\
Then the easiest way si to use something like file.io - click upload file, Find and select the save, share the url here.
Let me guess, all the raiders spawning in the east would path through the lake and through that little island, hitting all the traps? That is just so rimworld.
Gotta respect the terrain! Though id be building inside that mountain on the left
