[RMVX ACE] OVERLAY MAPS AND WORATANA'S FOGS - NOT WORKING

I'm having trouble getting Tsukihime's Overlay Map script to work well with Woratana's Fog script. I can get them both to work, but the fog doesn't show up on top of the overlay map - so the overlay map has no fog on it.
I made a little demo to illustrate it:

Has anyone gotten these things to work together? I've made a number of overlay maps that form tops of walls and large buildings, so no fogs on them looks dippy. I'm stuck with either no fogs (meh, not ideal) or redesign my maps.

I wouldn't mind redesigning the maps, except my tall sprite cut through tops of tiles.

Edit: Seems I stumped everyone? Well, in case anyone else has this problem... I ended up dumping Hime's Overlay Maps. It's a cool script, but I found that just doing some limited parallax mapping and getting a "fix parallax" script worked just as well, even if organizing the switches for the overlay graphics was more complex. But at least the fancy fogs are working, as is my smooth camera script. On the whole, an improvement. It helped with lag, too!
