This mod touches so many files and changes so many things, that it is unfortunately quite incompatible with most other submods. The only ones that seem to work without issues are the monument mods.

You can try to replace a file in the mod, it's events/DiggyDiggyHoleEvents.txt. Copy it from guibennar mod to this one. It's a fairly straightforward approach, but it works, although I don't know what the potential problems might be

It also overwrites some of the dwarven event files to deal with holds getting damaged/destroyed via events. So if you want to use GUIbennar you actually have to write (and maintain) a compatibility patch. Which sucks.
