Datagrid Wierdness

NVM the stack itself is bad. I began to experience wholesale data grid problems where the data grid displayed nothing the contents tab of the data grid properties displayed nothing, but fields I populate from the data grid data were in fact populating, meaning the data was actually in the data grid, but not displaying. 

When I replaced the stack file with an older backed up version, it worked fine.
