Map check occasionally fails on Tier 17 maps

[mkfink]

Very occasionally, when I press the Map Check hotkey over a T17 map, instead of showing the background (semi-transparent) and the map mods window, it only shows the background. The map mods window doesn't appear, no error message or anything. I do know that every map I've had this problem with had "of Storage" (barrels), but that's because those are the only ones I'm running map check on as I'm rolling them. This is on version 3.24.10004. Here's a map that the issue is happening with:
