Anyone having thoose two files in their mods, has to update thoose files accordingly. Patch 1.8 broke mods based on thoose files. Make sure to get the files from the Update.bsa, not the Interface.bsa.

I recon affected mods are...

Coloured Map Markers
LiHud+Map
Immersive Hud

...and pretty much any other mod that makes changes to map and/or map markers.
