So, my grid unitframes are GONE and are NOT resetable. What I CAN do is press something that would otherwise affect the looks of grid, such as height, width, even padding and space, it does appear, in the top left corner. HOWEVER, the unitframes are black and unmovable. When I reload ui, they're gone again. Wtf to do, is the question. Cheers.
Edit: Tried all versions of grid, disabled all other addons and reinstalled it quadruple times.
Delete the grid.lua and the grid.lua.bak file in your SavedVariables folders (WoW\WTF\Account\<acctname>\SavedVariables\grid.lua and grid.lua.bak) to reset your Grid setups.
