so im remaking a stock map but trying some stuff out.
i copied the TAT folder from assets/worlds to data_***/worlds then munged with the TAT folder selected and common selected but the munge is failing. when I replace the stock tat2.lvl with the new one and i load up the map there is just a big black void

to remake a default level you have to delete everything in the _LVL_PC folder that is in data_*** then when you munge, first clean, then munge with the common box checked
