So I went ahead and upgraded my 47.05-r11 LNP installation to the last (R8) dfhack version and I get almost constant:
...05-r11\Dwarf Fortress 0.47.05/hack/scripts/unsuspend.lua:130: attempt to index a nil value (local 'bld')
stack traceback:

Doesn't seem tied to anything I am doing, although I really don't know what widgets I should even see or not see. The one from R7 that was kinda handy is gone. I looked at the mouse coordinates one briefly but decided it was kinda useless and turned it off. The rest I don't know what/where they are.
It also seems a bit unstable, particularly it is crashing on saving which is annoying AF, although it seems tied to the latest migrant wave.
