Setting up 185 (or A73) "Not Out of the Woods Yet" on VASL is quite a pain. Although you can crop the boards as the scenario card advises, it's actually preferable not to, because there is important board-edge and just-off-board terrain that you will lose if you do so -- e.g., hexsides 6Q1-R0 and 6Q1-R1 are bocage, which is quite important given that German reinforcements can enter crossing those hexsides. Unfortunately, as soon as you start adding additional hexrows to make all this visible, the map alignment gets hopelessly skewed. I finally arrived at a somewhat satisfactory solution by setting up bd39+spare board on top row and bd00+bd06 on bottom row; bd39 is cropped P-GG, "spare board" is cropped A-B, bd00 is cropped FF-GG, and bd06 is cropped A-R.
Second problem is that the overlays along the join between bds 39 and 06 (O5, Wd1 and M2) only show up on the board they are placed on. To have them show up on both boards you have to place each one twice, e.g., O5 is placed normally as 39CC10-DD10, and then placed again as 06M0-N0.
Finally the hedges and walls all transform to bocage, except that on board 06 transformed walls look like off-colour walls, and transformed hedges look like off-colour hedges. Since they're both supposed to be the same terrain type, shouldn't they look like the same terrain type?
I don't know that there's any easy VASL solution for any of these issues, but thought it worth mentioning.
